Minimalist Service E-Commerce Site

I need a clean, distraction-free e-commerce website focused on selling my professional services. The entire user journey—from browsing service packages to checkout—has to feel effortless on both desktop and mobile.

Here’s what I have in mind:

I’ve developed an app on Replit for encrypting messages, and I would like to integrate this app into my website (please see the attached file for reference).

The website will consist of a few pages, including an introductory page and a minimalist sign-up page that requires a name, username (email) and password.

Payments will be processed through Bitcoin. Since I prefer not to use a payment processor, I will manually change the Bitcoin reception address for security reasons. We should discuss this aspect further.

In addition, there will be two more pages: one for the app and another for a forum where users can create folders and subfolders to leave messages.

The whole website should be https.

I already have the Domain name and I can provide my Replit information to merge the app on the website. I also have the instruction from Replit to merge the app.

• A minimalistic visual style: plenty of white space, restrained typography, and a muted colour palette that keeps attention on the service descriptions rather than on flashy graphics.
• Clear service listings with tiered options, upsells or add-ons, and an intuitive cart/checkout flow powered by Bitcoin
• Simple content-management controls so I can update prices, descriptions and images myself without touching code.
• Responsive layouts developed with modern standards (HTML5, CSS3, perhaps Tailwind or Bootstrap if it speeds things up) and light SEO optimisation for my core keywords.

Acceptance criteria
• Fully functional e-commerce flow: select service → cart → secure payment → confirmation email.
• Pages load quickly and look consistent on Chrome, Safari and Firefox, as well as iOS and Android.
• All copy, images, and colours align with the minimalist brand guide I’ll share.
• Final hand-off includes source files, clear instructions for routine edits, and 30-day post-launch support for minor fixes.

If this aligns with your expertise, let’s discuss timeline and any questions you may have.
