Merchant cash advances would probably be a good fit for that aspect.
There is a lot of money in that industry but the work is hard and long. There are no real short cuts so you would have to lay out a nice effective business plan, implement it, clean out the bugs and have something for your affiliates to use as a base to build their client base for you.
I was in that industry a bunch of years back (largest loan closed was 31.2 million) but the work involved and the stress associated with that world is something that I do not miss at all.
