question I'm looking to buy a website but need help

[fortxx]

The type of site i'm looking for is where
my members pay a single monthly fee auto pay in exchange for a product. This will be done with these member month to month until member cancels. This website is not a store but a club with members that pay monthly to continue membership and receive products.
what type of website would this be and does anyone know of any established website for sale offering this format.
I do not wish to be part of any affiliation.
