The verdict in three sentences
In Denver, a private jet and yacht charter website built by a local agency costs, as a 2026 ballpark, between 12 000 and 45 000 USD, and more once a real-time quoting engine or a client portal enters the brief. Kolonell builds route and destination pages, a manually updated empty-leg page, a qualified request form and clear broker disclosures for a fixed 2 900, 4 900 or 8 900 USD, delivered in 3 to 4 weeks on Starter and Growth. For a Colorado broker, the deciding factors are usually the launch date before ski season, the three-year total cost and whether the site states plainly who operates each flight.
How do Denver agencies, freelancers and Kolonell compare on price?
These ranges are prudent ballparks, not official figures. They are based on public rate cards of Colorado agencies, minimum project sizes on Clutch.co profiles of Denver studios (frequently 10 000 USD and up), hourly rates published by local agencies (often 120 to 180 USD per hour) and freelancer rates listed on Upwork. Studios that specialise in luxury or aviation brands tend to sit in the top half of the range.

What does a charter site need in Denver, a city with no sea?
Denver has no coastline, so a local charter business is mostly private aviation: on-demand flights from Centennial Airport, Rocky Mountain Metropolitan Airport or Denver International toward Aspen, Eagle County (Vail), Telluride, Jackson Hole or Scottsdale, plus business trips for energy, aerospace and private equity executives. When a Denver broker sells yacht charters, those charters take place elsewhere, typically in the Caribbean or the Mediterranean, for Colorado clients, and the site should say so clearly rather than imply a local marina. Useful pages:
- routes and destinations with typical flight times and seasonal notes (winter ski peaks, summer festivals in Aspen and Telluride);
- aircraft categories (turboprop, light, midsize, super-midsize jets) with honest notes on mountain airports, where runway length and altitude can affect which aircraft suit the trip;
- an empty-leg page you update yourself from the site's admin;
- a qualified request form: route, dates, passengers, luggage and skis, pets, flexibility, indicative budget;
- a safety and operators page explaining how you select operators;
- yacht charter pages for Caribbean and Mediterranean trips if you offer them, with no destination you do not actually serve.

An automated empty-leg feed, instant pricing, an online booking engine or a connection to charter management software is a custom application, quoted on request. Ongoing search work is quoted on request too.
Which three-year cost should a Denver broker compare?
The table keeps the same maintenance assumption on both sides, since Kolonell maintenance after the support period is quoted on request.
| Item over 36 months | Denver agency (mid range) | Kolonell Growth |
|---|---|---|
| Website build | 24 000 USD | 4 900 USD |
| Support included after launch | Depends on contract | 3 months included |
| Maintenance (same assumption) | 180 USD per month over 33 months, 5 940 USD | 5 940 USD, quoted on request |
| 6 new destination pages over 3 years | 12 hours at 150 USD, 1 800 USD | Quoted beforehand, assumption 1 200 USD |
| Licensed aircraft imagery | 900 USD | 900 USD |
| Indicative total | 32 640 USD | 12 940 USD |
Use these lines to compare quotes side by side; they do not predict your final invoice.
Which rules shape the wording of the site?
In the United States, on-demand charter flights are generally operated under FAA Part 135 by an operator holding an Air Operator Certificate. A broker does not operate aircraft, must not present itself as the operator and should state who operates the flight. The Department of Transportation also has rules on how air charter brokers advertise and disclose their role; your counsel can confirm how they apply to your wording. On yachts, a commercial charter follows the rules of the flag state and of the cruising area, and Mediterranean charters often use a standard MYBA contract; keep these pages factual and refer clients to the contract. On data, Colorado has its own consumer privacy law, the Colorado Privacy Act; collect only what you need at first contact and never ask for passport copies through a web form. For accessibility, the ADA is the legal backdrop and WCAG 2.1 AA the technical reference. This is not legal advice.

Which warning signs should you catch in a quote?
- A fleet gallery of aircraft you do not operate, shown as yours.
- An instant price calculator bundled into a showcase site at no extra cost: either it is a toy, or the real cost is hidden.
- Stock photos of aircraft with visible tail numbers and no licence.
- Client names or celebrity hints in case studies: discretion is part of the product.
- Domain or hosting registered by the agency.
- No date for the launch: a site that misses December misses the busiest weeks.
Mini case study
Illustrative example. Marcus T. left a larger brokerage to launch his own two-person firm in Greenwood Village, focused on flights to Aspen and Vail and on Caribbean yacht charters for Colorado families. He wants the site live before the first ski weekends. His three quotes:
- Denver agency: 26 000 USD, 12 weeks, which lands after the season opens.
- Denver freelancer: 8 000 USD, 8 weeks, copy to be written by Marcus.
- Kolonell Growth: 4 900 USD, 3 to 4 weeks, plus 600 USD of licensed aircraft imagery.
Kolonell route: 4 900 + 600 = 5 500 USD, against 26 000 USD with the agency, a gap of 20 500 USD, and against 8 000 USD with the freelancer. In return, Marcus gathers operator permissions for images himself and accepts calls in his morning.
FAQ
How much does a private jet charter website cost in Denver?
As a 2026 ballpark, a Denver agency charges 12 000 to 45 000 USD and up, a freelancer 4 000 to 11 000 USD. Kolonell charges a fixed 2 900, 4 900 or 8 900 USD.
Can we publish empty legs ourselves?
Yes, from Growth at 4 900 USD the empty-leg page is edited from the admin in a few minutes. An automated feed from operators is a custom application quoted on request.
Denver has no sea: should we mention yacht charters at all?
Yes, if you arrange them, as long as the page states where charters take place, for example the Caribbean or the Mediterranean. Inventing a local port would damage trust in seconds.
Will the site explain that we are a broker?
Yes, every tier includes a page and footer wording on your role and on who operates the flights. Have your counsel review it before launch, which usually takes 1 or 2 days.
How do calls work with the time difference?
The team is on GMT, 6 to 7 hours ahead of Denver. Calls are scheduled in your business hours and you receive one written update per week.
Let's scope your project. Send us your routes, aircraft categories, yacht destinations and target launch date, and we will confirm a fixed price in USD with a 3 to 6 week timeline. Request your free quote or see the international offer.
