To run a lending service you need to build your reputation and be as professional as possible in your service. There is already quite a few lenders on the forum with high reputation, competing with them is a challenge, more so for an unknown newbie.

Depends on your interest %. It ranges for different services.

If you are asking this question then do so. Appraising those requesting a loan to determine who to offer a no collateral loan and who not to would complicate your service, you might also not be able to recover from the loss of a defaulted loan.
