I'll give a pretty radically different way you COULD try this.
Your site is built with a few pages. Primarily to serve as a landing page, purchase page, and maybe news or something.
No login needed!
Your payment page can be facilitated through any payment system you like. That payment system has something like a zapier integration that shares access to a google drive, dropbox, etc where the videos are stored, and an email is sent to the user notifying them.
Your payment and email system serve as customer records, your hosting of videos is file-based and if you want your static site to summarize whats available that's fine too.

that could definitely be an MVP
