Personal PayPal Loaning

I am looking for someone who can inform me of how a site for personal loans through PayPal could be established. As this will only be a really small service I distribute to a small community. I don't intend on anything legal to be processed. I am looking for someone that can evaluate the best solution as to how I can ensure safely lending money to people, and then having a small website (or even page, if that simple) created where loans can be requested and otherwise handled with PayPal.
