I have a Patreon page which works like a VIP thing. In other words, drummers wanting advanced lessons can sign up as "patrons" and get what they want.
Anyway, this whole thing simply hasn't had enough time/cash for development - so no takers. Well, I do have a lot of free content, but there isn't enough paid stuff - and also enough marketing (building a list, buttering up the list etc..).
O.K., as a final thought. VIP memberships aren't always about profit, though. Some owners just need to pay maintenance costs. Is that anyone's situation?
