Five things we build.
The same team plans, designs, builds, and keeps the thing running — nothing is handed to a third party halfway through. Every case below is a live URL you can open, and before you sign anything, we can build you a working screen.
- Corporate websites & landing pagesCompany sites that survive the three-second credibility check. We plan the route to the enquiry first, then design on top of it.
- Custom web applicationsAccounts, permissions, payments, and an admin console your team can operate — the half of a product that decides whether it survives real use.
- Ecommerce & direct-to-consumer storesA store you own outright: catalogue, checkout, stock, promotions, and settlement in one place, run from an admin built for the person doing the work.
- Website redesign & replatformingRebuild on current foundations without losing what you already earned — content, URLs, and search rankings all move across.
- Maintenance & ongoing supportMonitoring, fixes, and improvements after launch — including sites we did not build, when the original agency has stopped answering.
How we quote
Most projects fall between $1,500 and $6,000, fixed price. You get an itemized scope of work, milestones with dates, and a single number before anything starts — no hourly billing and no open-ended line items. On final payment, source code, design files, the domain, and hosting accounts all transfer to you.
Not sure which of the five you need? Describe the problem in two sentences and we will tell you — including when the answer is that you should not build it yet.
