The API would be something to engage a developer to assist with. If this is for students, I assume you have some sort of roster with user accounts. You could have a developer write a script that would take a list of accounts and create a club for that user, make them the admin of that club, do some basic setup, etc.
Otherwise, you could manually do it.... but when you're talking about hundreds of students, that's a LOT of work to create by hand.
