These guys own
http://fullhentaimovies.com, which
has some cosplay content. However,
http://fullhentaimovies.com has not been added to it officially, and the program itself needs a fairly hefty update.
They said if you're interested in promoting fullhentaimovies (and have an affiliate account setup with ccbill), they could manually generate an affiliate code for you.
