Is there a way to charge customers to become members of my Gallery?

I am working on a possible site where I will charge members of a particular community to "join" my gallery site, thus giving them access to the images.

Their access would allow them to view/download/order prints etc... (all of which I know how to configure in my existing gallery2 installation).

I just want to make certain galleries available only to the exclusive members who have paid to join giving them unlimited access.

Any suggestions?
