I have spent a lot of time thinking about this very subject, and have in fact made a few small stabs at solving it.

Here's one way I think would work: Start as a matchmaking service. A severe, almost crippling problem that many dating sites have is that a great deal of the listings are, in one way or another, not in good faith: scammers, liars, fakes, people who are fantasizing about leaving their spouses but will never get up the nerve to do more than waste other people's time, etc. So you can start as a participant on one of those sites, and get yourself a list of contacts, and start vetting them for sincerity. It would help a lot if you can take a "boots on the ground" approach. For example, if the site is for American dudes to hook up with Chinese women, then you should hire an assistant in a major Chinese city who can interview the women in person.

Eventually, you'll have a deep enough bench that you can open up the site to more traditional participants.
