Website design for Los Angeles, delivered remotely

We take on website work for Los Angeles businesses remotely from Malvern, PA, and every stage is reviewed in your own browser.

Why it matters: 411,949 business establishments operated in the metro in 2023, and 88% of them employed fewer than 20 people.

Go deeper: how a remote build runs, stage by stage

Health care and social assistance alone holds 15.2% of the 5,568,514 paid employees counted in the metro in 2023.

Accommodation and food services adds 11.6% and retail trade 10.2%, so three sectors hold 36.9% of the payroll count.

The three cards above are the three largest of the 12 sectors we read for the metro, by paid employees: health care and social assistance, accommodation and food services and retail trade.

Professional services is fourth, with 471,294 paid employees in 61,848 establishments.

  1. Health care

    845,665 paid employees across 53,869 establishments in 2023; a site here needs online booking, intake forms and an accessible path for every patient.

  2. Hospitality and food

    643,243 paid employees across 34,060 establishments in 2023; a site here needs hours, menus and bookings that read on a phone in a hurry.

  3. Retail

    566,614 paid employees across 38,838 establishments in 2023; a site here needs stock that matches the till and a phone checkout.

Websites we built

Six live sites we built open here in a preview window, the same way your build is reviewed before launch.

Why it matters: A working site shows how a build loads, reads and takes an enquiry, which no mock-up can.

Go deeper: how the previews work

Preview opens the live site inside a sandboxed frame on this page. Atlas Peptides blocks framing, so its preview is a dated screenshot instead.

None of the six is presented as a Los Angeles business; each one shows a job a site has to do, whatever the city.

Between them they cover a configurator that prices as you build, online scheduling, booking with reviews pulled in, a shared stock count, a quote form and a checkout.

411,949 businesses, in public numbers

The metro had 411,949 business establishments in 2023, +8.6% since 2018, by County Business Patterns.

By the numbers: 12,927,614 people lived in the metro in 2024, −2.2% since 2019, and payrolls counted 5,568,514 employees.

Go deeper: what County Business Patterns counts

Of the 411,949 establishments, 362,690 had fewer than 20 people and 41,077 employed 20 to 99. Another 7,342 employed 100 to 499, and 840 employed 500 or more.

Within the 20-to-99 band, 30,732 establishments had 20 to 49 people and 10,345 had 50 to 99. The average establishment employed 13.5 of the 5,568,514 paid staff.

County Business Patterns counts employer establishments, locations with paid staff, so a sole owner with no employees is not in the 411,949; that is one establishment for every 31.4 residents.

NAICS 541511, custom computer programming, includes custom web page design and all other custom software, so 86.5 per 10,000 businesses is a ceiling on web-design firms in the metro.

Health care leads, with 845,665 employees

Health care and social assistance employed 845,665 people in the metro in 2023, the most of the 12 sectors we read.

Why it matters: who a site talks to follows the sector mix, and accommodation and food services comes next at 643,243 employees.

  • Health care: 15.7 employees per establishment; booking and intake matter most.
  • Hospitality and food: 18.9 employees per establishment; hours and menus must read fast.
  • Retail: 14.6 employees per establishment; stock and checkout must agree.
Go deeper: who these pages are written for

53,869 health care and social assistance establishments in the metro need online booking, intake forms and an accessible path for every patient. The 34,060 in accommodation and food services need hours, menus and bookings that read on a phone in a hurry.

Retail trade counts 38,838 establishments that need stock that matches the till and a phone checkout, and professional, scientific and technical services, fourth at 471,294 employees, needs proof of expertise, case pages and a routed enquiry form.

Manufacturing ranks fifth at 435,021 employees, and the 12 sectors we read cover 4,770,466 of the 5,568,514 paid employees in the metro.

Together the four employ 2,526,816 people, 45.4% of the payroll count; the sector figures shape the scope, and the six sites above are our delivered work.

3,565 custom programming firms in the metro

3,565 custom computer programming establishments (NAICS 541511) operated in the metro in 2023, +3.2% since 2018.

Yes, but: that code also covers all custom software, so 86.5 per 10,000 businesses is a ceiling on web-design firms, not a count.

  • Graphic design (NAICS 541430): 1,463 establishments in 2023.
  • Marketing consulting (NAICS 541613): 4,870 establishments in 2023.
  • Advertising agencies (NAICS 541810): 1,401 establishments in 2023.
Go deeper: how to compare the firms on your list

With 5,028 programming and graphic design establishments in the metro, ask each firm for live sites you can open, who will own the code and domain, and a written scope.

The wider NAICS 5415 group, computer systems design and related services, counted 7,006 establishments, 170.1 per 10,000 businesses.

Marketing consulting (4,870) and advertising agencies (1,401) often sell websites too, so the full field in the metro is wider than the programming count.

Custom programming establishments went from 3,454 in 2018 to 3,565 in 2023, while graphic design stood at 1,463, 35.5 per 10,000 businesses.

Those 3,565 programming firms employed 29,666 people, about 8.3 each. The wider 5415 group employed 57,977.

From 379,268 to 411,949 businesses since 2018

Establishments in the metro rose from 379,268 in 2018 to 411,949 in 2023, a change of +8.6%.

The bottom line: health care and social assistance grew the most of the 12 sectors, +16.8% in establishments, while manufacturing moved −10.1%.

  • 20 to 99 employees: 41,317 establishments in 2018, 41,077 in 2023.
  • 100 to 499 employees: 7,408 in 2018, 7,342 in 2023.
  • 500 or more employees: 810 in 2018, 840 in 2023.
Go deeper: what the change means for a website

Health care and social assistance went from 46,116 to 53,869 establishments between 2018 and 2023; manufacturing went from 16,020 to 14,403.

Educational services came second, +15.9%, and professional, scientific and technical services third, +15.2%.

That is a net gain of 32,681 establishments: each new one needs a first site, and each established one carries addresses and rankings a rebuild must keep.

Paid employees went from 5,400,184 to 5,568,514 over the same years, +3.1%. Population moved −2.2% from 2019 to 2024, to 12,927,614.

Ranked 6th of 64 places by businesses

The metro ranks 6th of the 64 places we build pages for by business establishments, and 32nd for programming firms per 10,000 businesses.

By the numbers: population growth since 2019 ranks 63rd of 64, and the share of establishments under 20 staff ranks 5th.

Go deeper: why every place is measured the same way

Every place page uses the same Census tables, so these ranks compare like with like: 411,949 establishments here against the 64 places' own counts, 24th for their change since 2018.

Programming firms run 86.5 per 10,000 businesses here against a median of 85.2. The under-20 share is 88% against 84.4%.

The 64 are the places whose web design searches clear 500 a month in Semrush's exact data, state pages counted with any places folded in; this one draws 3,140, 5th of the 134 places we measured nationwide.

How a Los Angeles web project runs

A project here runs in the same five stages as every build of ours, from agreeing what the site is for to launch.

What you get: the scope, price and schedule in writing at stage two, before anything is designed or built.

Go deeper: what happens at each stage

Stage one fixes who the site talks to; in the metro, where health care and social assistance employs 845,665 people, that answer often sets the integrations.

Stage five hands the site over in your own accounts, a handover any of the 7,006 systems design establishments in the metro could pick up from.

For the 34,060 accommodation and food services establishments here, stage two usually lists hours, menus and bookings that read on a phone in a hurry.

The five stages in order; the written scope, price and schedule come at stage two.
  1. Agree what the site is for

    Who the site talks to, what it must get them to do, and what it connects to.

  2. Scope, price and schedule in writing

    Pages, integrations, price and dates on paper before any design starts.

  3. Design in the browser

    Real content at real widths, reviewed on your own phone as it takes shape.

  4. Build and wire it up

    Code, forms, CRM, analytics and accessibility checks, in one pass.

  5. Launch, hand over, stay on

    The site goes live in your accounts, and we stay on for support.

Working with us from Los Angeles

Los Angeles runs on Pacific time, so our 9-to-5 Eastern day is 6 a.m. to 2 p.m. there.

The bottom line: the office answers (610) 890-9711 Monday to Friday, 6 a.m. to 2 p.m. local time, the day 3,565 programming firms here keep.

Do you have an office in Los Angeles?

No. Our one office is in Malvern, PA, and projects here run remotely, with every stage reviewed in your own browser.

Go deeper: calls, reviews and where the work happens

Calls and screen-shares cover the whole build, and you review the work in your own browser between them; no branch office or answering service sits in between.

Web design questions from the metro

Not answered here? Call the office: (610) 890-9711

Yes. We take on website work for Los Angeles businesses remotely from Malvern, PA, and every stage is reviewed in your own browser. You deal directly with the people designing and coding the site, and calls are set in Pacific hours, the clock the metro's 411,949 establishments keep.

The scope sets the price, not the ZIP code: pages, integrations and what the site must do, for one of the 362,690 small establishments here or a larger one. You get the price and schedule in writing first; advertisers paid about $8.00 a click for the main web design phrasing here (Semrush).

Hire a designer when the site has to book, quote, sell or connect to a CRM; a builder fits a site a standard template can serve. In the metro, 88% of establishments employ fewer than 20 people, so we say which route fits before quoting anything.

Yes. Titles, headings, page speed and schema go in while the site is built, and Search Console is connected at launch, so the 3,140 monthly searches (top phrasing 1,900) in the table above are targeted from day one. “web design los angeles” alone draws 1,900 a month, by Semrush’s count.

Yes. That kind of site is scoped like any build of ours: service-area pages, project photos and quote requests that land in the office inbox, each part priced in writing before work starts. The metro had 25,486 construction establishments in 2023, by County Business Patterns.

Yes. That kind of site is scoped like any build of ours: a catalogue, stock that agrees with the counter and a checkout that works on a phone, each part priced in writing before work starts. The metro had 38,838 retail trade establishments in 2023, by County Business Patterns.

Open the live sites a firm has built, ask who owns the code, domain and hosting, and get the scope and price in writing. With 5,028 programming and graphic design establishments in the metro, and 86.5 programming firms per 10,000 businesses, those three checks shorten the list quickly.
