My sister is trying to set up a website which will primarily be video courses behind a paywall. She has found a plugin to work with her (old)Wordpress site, called Ruzuku. She is now using Concrete5 for her main site I think, but if WP is the only option, she will happily set the new site up on it. Does anyone else know of similar plugins? She is on a very tight budget for this project which is why she is trying to do this herself.
