I want a simple theme/website to sell just one online course

I want a nice-looking, fast theme for a website where I want to sell just one online course paid via PayPal. Hopefully, something that has all the options needed and doesn’t need a million additional plugins for it to work. Something with an easy back end for me to set up the course. Any suggestions, please? Thanks

Hm, that’s more of a shop than somewhere people could login and access a course I think? Perhaps I wasn’t clear. Thank you
