Working together
Clear steps. Close collaboration.
- 01
A conversation.
Tell me what you need. We agree on the result, a fixed scope, a price, and a start date.
- 02
Something to react to.
You see the design and working progress early. We refine it together, with one person to talk to.
- 03
Yours to build on.
Your website goes live or your app reaches testers. You get the code, accounts, and a clear handover.
What does the $500 website include?
One custom page, designed for mobile and desktop, with your services, proof, and a contact form or booking link. Search foundations, one revision round, deployment, and the source code are included. You supply the business details and assets; domain, hosting, paid assets, and applicable taxes are separate.
Will I work directly with you?
Yes. I’m Vaclav, and HLT3 Studio is my one-person business. I handle the conversation, design, engineering, and handover. We agree a realistic start date before you commit.
What if I’m not sure what I need yet?
Rough notes are enough. Send a short message or book a free 20-minute call. We’ll work out the useful first step, the likely budget, and whether I’m the right person to build it. There is no commitment to a project.
