Well, if your using TGP submitter from Chamelon, they also have a partnership submitter which will help in getting partnership accounts at some of the TGP sites. You will need to have samples of some of the galleries you have submitted and sometimes where they are listed. The TGP's that get the most traffic charge monthly for partnership accounts. Some are around $15-$20 per month and some are even more. You can apply for those via the parntership submitter, or manually by going to some of those sites or also at
