Hello,
Our cart would not be optimal for this sort of business as all of the funds from your sales go directly to you, and we have no tools to forward on any portion of that revenue or calculate the earnings of any particular partner/artist that you are working with. Our affiliate system can't be used for this purpose because that will credit a single person at most and won't work in situations where a buyer purchases items that should be credited to different individuals.
I'd recommend looking elsewhere online, perhaps an installed shopping cart would be able to include the features you need.
