Just found this site online!
It seems that Paypal has a site where people offer money for "doing stuff"! One example is someone offering $20 to clean their room!
Paypal calls it "doing stuff for money".
How it works is that you enter your name, the person's name who you are making the offer to, how much you are offering and what it is that you want done.
So far I haven't found any "open" invitations - meaning you have to specifically enter in someone's email address instead of making your paypal offer open to everyone.
