E-Commerce Service Sales Website

I already have the core pages for my site live at https://investments2026.tilda.ws/. Now I need an experienced developer to turn it into a revenue-ready e-commerce platform focused on selling services.

What I’m aiming for
• 100 % e-commerce flow: visitors should be able to browse service packages, add them to cart, and check out seamlessly.
• Digital fulfilment: once a purchase is complete, the buyer must receive any supporting files or materials through a secure downloadable content delivery system.
• License management: certain services include licensed resources; I need automatic generation, tracking, and revocation of license keys.
• Subscription plans: some offerings renew monthly or annually. Customers should be able to start, pause, cancel, and update payment details from a self-service dashboard.

Preferred approach
The front-end look and feel on Tilda can stay, but I’m open to migrating or integrating a back-end that cleanly covers payments, subscriptions, and license handling (Stripe, Paddle, Lemon Squeezy, or another proven solution). I value clean code, GDPR-compliant data handling, and clear documentation so I can manage basic updates myself later.

Deliverables
1. Fully functional e-commerce implementation on the live domain.
2. Admin interface to create/edit service listings, license rules, and subscription tiers.
3. Automated email confirmations with download links or license keys.
4. Short written guide (or screen-recorded walk-through) showing how to manage orders and subscriptions.

If you have direct experience building service-based storefronts with downloadable content delivery, license management, and recurring billing, I’d love to see examples.
