Finalize HTML Site & Payments

My static HTML site is almost ready to launch; the last pieces are a reliable checkout flow and a working Splitforms submission. I already hold live Stripe and PayPal accounts and will provide the API keys, webhooks, and any credentials you need.

What I need from you:
• Wire the existing “Buy Now” / “Subscribe” buttons to both Stripe and PayPal so customers can choose either option without leaving the site. One-off charges are all that’s required—no marketplaces or advanced billing logic.
• Ensure successful payments trigger the confirmation page, email receipt, and basic order log I’ve sketched out (JSON or MySQL is fine).
• Track failed or abandoned payments cleanly.
• Debug and repair the Splitforms form so submissions reach my inbox and store a copy in the same log as paid orders.

I’ll share the codebase along with a short video walkthrough so you can see the current structure. When you reply, include links to past projects where you connected both Stripe and PayPal to an HTML or JavaScript front end—those examples will weigh heavily in my choice.

Once everything runs smoothly on your test server, push a clean commit and I’ll verify on my host before we call it done.
