Functional Testing to be done for a social networking site

You need to do testing of a social networking site to make sure all the functionalities of the site are working fine as needed. We have implemented a referral system in which members are get paid for direct referrals as well as indirect referrals upto 6 level. So you need to create profiles and do the thorough checking of the referral system and make sure it is working as per the requirement. Also you will need to create that much emails too, as rererral count matters only if email verification is done. I think, this doesn't need any particular skill or anything to bid on. You find the errors and we are happy to pay you for that. Only testing to be done on the site functionality only. No code level testing nothing to be done.
