There is the possibility for you to start out your own lending company here, and you can build trust in the forum. But you must, of course, to use escrow before going to get trust out of the people. But that's just my opinion about it.
There are some guys here with a lending business, but they can't make a real good profit unless they got big clients who come back on a regular basis.
If you only have micro loans, the risk vs reward vs time you invest, will in no way be profitable.
