Ecommerce recommendations

Anyone know of any ecommerce solutions that don’t necessarily deal with selling physical products. The site I’m working on is a sports handicapper site, so all they provide is information on who’ll they think will win certain sports games (NCAA, NFL, MLB). I need a solution that a user can basically purchase (using a credit card) time to the site.

Say they purchase a package for 3 days use, then after they pay they will have access to the site for 3 days and then their access will be terminated.
I guess you could say it’s how a **** site would work (not that I would know :wink: ). But all the ecommerce co.'s like storefront and monstercommerce seem to cater to businesses that sell products and the like.

Anyone know of anything?
