Hi Profitsee,
I'm not sure that I completely understand what you're looking for, but by using the words "private lenders", it sounds like you're looking to be hooked up with people who have money to lend off of the site. (Am I understanding you correctly?) If that's the case, it's up to you to make it happen, but not likely something we will pursue on Prosper.
Part of the founding principle of Prosper is that borrowers and lenders can have complete anonymity. Money and credit are sensitive issues for most people, and although there are some borrowers (like yourself) who might be very public, we think most people would rather not have their identity disclosed.
Best regards,
Andrew
