312060 Universal Class clone

Looking for a script to do the functions that run the site [login to view URL] Design is not important, but functions are. I would prefer one already completed if you have one done. Send me demo in PMS. Does not have to be as detailed, but need the same basic functions. This will be for a Christian learning site. I do not need web design, but just a functioning script. Users will need to join the site. Once they have joined, they can either join existing classes or start thier own classes as a teacher. As a teacher of the class, they should be able to make lesson plans in html or text. They should also be able to give test which would be multiple choice or T/F and the test should grade itself. There should be also a discussion board for each class. They can decide whether to make the class a paid or free class. If paid, they determine the cost. Teacher can approve or delete class list and the class itself. As an admin, I can set to approve teachers or have them automatically allowed to set up classes. If teacher decides their class is a paid class, then it credits to my account through paypal and I pay the teachers. Admin able to delete or edit classes and/or users. There are several open source project similar to this at: [login to view URL] but none of them have all the features mentioned above. (TWO MORE THINGS) I know my max is low, but that is all I have for this project) Please only bid if you believe you can complete this. I had posted this a while back 3x, and each time the programmers were not able to complete once that got started.
