Website design for Colorado, delivered remotely

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

Why it matters: 182,486 business establishments operated in the state in 2023, and 87.1% of them employed fewer than 20 people.

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

Health care and social assistance alone holds 13.7% of the 2,566,040 paid employees counted in the state in 2023.

Accommodation and food services adds 11.9% and retail trade 11.4%, so three sectors hold 37% of the payroll count.

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

Professional services is fourth, with 243,578 paid employees in 28,143 establishments.

  1. Health care

    352,483 paid employees across 19,456 establishments in 2023; a site here needs online booking, intake forms and an accessible path for every patient.

  2. Hospitality and food

    304,455 paid employees across 15,405 establishments in 2023; a site here needs hours, menus and bookings that read on a phone in a hurry.

  3. Retail

    292,486 paid employees across 18,589 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 Colorado 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.

182,486 businesses, in public numbers

The state had 182,486 business establishments in 2023, +5.8% since 2018, by County Business Patterns.

By the numbers: 5,957,494 people lived in the state in 2024, +3.5% since 2019, and payrolls counted 2,566,040 employees.

Go deeper: what County Business Patterns counts

Of the 182,486 establishments, 158,986 had fewer than 20 people and 19,792 employed 20 to 99. Another 3,304 employed 100 to 499, and 404 employed 500 or more.

Within the 20-to-99 band, 14,990 establishments had 20 to 49 people and 4,802 had 50 to 99. The average establishment employed 14.1 of the 2,566,040 paid staff.

County Business Patterns counts employer establishments, locations with paid staff, so a sole owner with no employees is not in the 182,486; that is one establishment for every 32.6 residents.

NAICS 541511, custom computer programming, includes custom web page design and all other custom software, so 117.6 per 10,000 businesses is a ceiling on web-design firms in the state.

Health care leads, with 352,483 employees

Health care and social assistance employed 352,483 people in the state 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 304,455 employees.

  • Health care: 18.1 employees per establishment; booking and intake matter most.
  • Hospitality and food: 19.8 employees per establishment; hours and menus must read fast.
  • Retail: 15.7 employees per establishment; stock and checkout must agree.
Go deeper: who these pages are written for

19,456 health care and social assistance establishments in the state need online booking, intake forms and an accessible path for every patient. The 15,405 in accommodation and food services need hours, menus and bookings that read on a phone in a hurry.

Retail trade counts 18,589 establishments that need stock that matches the till and a phone checkout, and professional, scientific and technical services, fourth at 243,578 employees, needs proof of expertise, case pages and a routed enquiry form.

Administrative and support services ranks fifth at 214,724 employees, and the 12 sectors we read cover 2,176,098 of the 2,566,040 paid employees in the state.

Together the four employ 1,193,002 people, 46.5% of the payroll count; the sector figures shape the scope, and the six sites above are our delivered work.

2,146 custom programming firms statewide

2,146 custom computer programming establishments (NAICS 541511) operated in the state in 2023, +0.1% since 2018.

Yes, but: that code also covers all custom software, so 117.6 per 10,000 businesses is a ceiling on web-design firms, not a count.

  • Graphic design (NAICS 541430): 529 establishments in 2023.
  • Marketing consulting (NAICS 541613): 1,854 establishments in 2023.
  • Advertising agencies (NAICS 541810): 401 establishments in 2023.
Go deeper: how to compare the firms on your list

With 2,675 programming and graphic design establishments in the state, 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 4,264 establishments, 233.7 per 10,000 businesses.

Marketing consulting (1,854) and advertising agencies (401) often sell websites too, so the full field in the state is wider than the programming count.

Custom programming establishments went from 2,144 in 2018 to 2,146 in 2023, while graphic design stood at 529, 29 per 10,000 businesses.

Those 2,146 programming firms employed 19,156 people, about 8.9 each. The wider 5415 group employed 55,523.

From 172,548 to 182,486 businesses since 2018

Establishments in the state rose from 172,548 in 2018 to 182,486 in 2023, a change of +5.8%.

The bottom line: health care and social assistance grew the most of the 12 sectors, +13.9% in establishments, while wholesale trade moved −5.2%.

  • 20 to 99 employees: 18,499 establishments in 2018, 19,792 in 2023.
  • 100 to 499 employees: 3,159 in 2018, 3,304 in 2023.
  • 500 or more employees: 370 in 2018, 404 in 2023.
Go deeper: what the change means for a website

Health care and social assistance went from 17,089 to 19,456 establishments between 2018 and 2023; wholesale trade went from 7,172 to 6,796.

Real estate, rental and leasing came second, +13.5%, and educational services third, +11.6%.

That is a net gain of 9,938 establishments: each new one needs a first site, and each established one carries addresses and rankings a rebuild must keep.

Paid employees went from 2,423,817 to 2,566,040 over the same years, +5.9%. Population moved +3.5% from 2019 to 2024, to 5,957,494.

Ranked 16th of 64 places by businesses

The state ranks 16th of the 64 places we build pages for by business establishments, and 15th for programming firms per 10,000 businesses.

By the numbers: population growth since 2019 ranks 39th of 64, and the share of establishments under 20 staff ranks 8th.

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: 182,486 establishments here against the 64 places' own counts, 31st for their change since 2018.

Programming firms run 117.6 per 10,000 businesses here against a median of 85.2. The under-20 share is 87.1% 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 570, 61st of the 134 places we measured nationwide.

How a Colorado 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 state, where health care and social assistance employs 352,483 people, that answer often sets the integrations.

Stage five hands the site over in your own accounts, a handover any of the 4,264 systems design establishments in the state could pick up from.

For the 15,405 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 Colorado

Colorado runs on Mountain time, so our 9-to-5 Eastern day is 7 a.m. to 3 p.m. there.

The bottom line: the office answers (610) 890-9711 Monday to Friday, 7 a.m. to 3 p.m. local time, the day 2,146 programming firms here keep.

Do you have an office in Colorado?

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 state

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

Yes. We take on website work for Colorado 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 Mountain hours, the clock the state's 182,486 establishments keep.

The scope sets the price, not the ZIP code: pages, integrations and what the site must do, for one of the 158,986 small establishments here or a larger one. You get the price and schedule in writing first; advertisers paid about $9.78 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 state, 87.1% 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 570 monthly searches (top phrasing 390) in the table above are targeted from day one. “web design colorado” alone draws 390 a month, by Semrush’s count.

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 2,675 programming and graphic design establishments in the state, and 117.6 programming firms per 10,000 businesses, those three checks shorten the list quickly.

Yes. We build to WCAG 2.1 AA: keyboard paths, contrast, labels and headings checked before launch, with no overlay and no certificate claimed. It matters most for the 19,456 health care and social assistance establishments in the state, whose patients include people of every ability.

Yes. 158,986 of the 182,486 establishments in the state had fewer than 20 employees in 2023, and every one of the six sites above is for an owner-led business. The scope starts with the one job the site must do, booked, quoted or sold.
