If you have experience, maybe try out in the lending board is something that may help. You can lend it using collateral in order to have a safer process... Try to get as much knowledge as you can before proceeding with it.
Lending with $100 for me is insufficient because if you are going to start out lending business you must really have a lot of capital.
Because if you are just going to hope with your profit to lending and that is your capital for sure it is not going to satisfy you.
Possibility of your profit with that amount is only low.
