Sell me a list of do follow social bookmarking sites

Hello, I need a list of do follow social bookmarking sites that allow free submission of links. The list must be verified though I shall check them myself before accepting the payout. The list must be no less than 50 sites, it is a 10 minute job for some who already has such a list. I shall accept only 1 bid check the list and release the payment. This is great way to get a 10 rating and a great review. Thanks
