Etsy like site with a 'dating site' spin

trying to create an etsy like marketplace where users can create their own ‘stores’ and sell products (through a front end interface, don’t want to give them admin access). but i’d also like to integrate a ‘dating site’ approach, where buyers and sellers create their own profiles and get matched to each other.
i can’t find a dating site plugin/theme that has an ecommerce component. currently using marketpress for the ecommerce piece on a multisite install.
anyone have any suggestions? doesn’t have to be a multisite install, just as long as users can create their own profiles and post their products for sale (but can manage all this through the front end).
thanks in advance!!
