WireGuard Provisioning & Payment Automation

I run a private WireGuard VPN service and I’m looking to automate everything that happens after a user clicks “Sign Up.” On a Linux server, I need a system that:

• Presents a clean web interface (or well-documented REST API) where visitors can purchase a subscription using credit/debit cards, PayPal, or cryptocurrency.
• Handles secure username-and-password account creation, then instantly provisions a unique WireGuard configuration and QR code for each paid user.
• Stores active accounts, keys, payment status, and renewal dates in a lightweight database.
• Suspends or deletes tunnels automatically when payments lapse, and reinstates them once payment clears.
• Includes an admin dashboard for manual overrides, user search, usage logs, and basic analytics.
• Ships with clear installation steps, environment variables, and a rollback/uninstall script so I can redeploy on another Linux box if needed.

A mid-level scope is fine: a functional prototype that’s secure, documented, and ready for me to harden and brand. Prefer modern tooling—Docker for packaging, WireGuard’s wg or wg-quick commands for key management, plus familiar payment libraries such as Stripe, PayPal SDK, or a crypto gateway of your choice.

Delivery should include source code (Git), an importable database schema, README, and a short video or screenshots demonstrating user sign-up through successful connection.
