Expert Integration of Stripe and Web3 Payments for Existing Website

I need a developer to integrate Stripe and Web3 payments into my existing website for selling access to an online wine course.

The project includes one-time card payments through Stripe and USDC payments through MetaMask and WalletConnect. Customers should receive course access automatically after successful payment verification.

Key requirements include a responsive checkout, secure server-side payment verification, webhook handling, email notifications, duplicate transaction prevention, and an admin page to manage payments and resend access emails.

The work also includes server deployment, domain configuration, SSL setup, and basic checkout-related fixes. The website should support cad $79 card payments and 58 usdc test payments on polygon amoy.

Please provide clean, secure code, test the complete payment flow, and include setup documentation.
