I need help to create a BIG membership site!

hello guys, I need to go BIG with this plugin.

I need help and good advise about this, How can I create a membership site like video2brain, I mean a site that has different multimedia courses.

I'm asking you for this because I need to track different payment for different courses, to know how much pay to the tutors based on the income the course generated.

I don't know how to cerate this, I don't want to offer access o the members to the whole site for the same monthly recurring payment. I'll several courses with different tutors.

Really needing a good help on this guys!

Thankyou in advance!
