See sig ... I can't recommend one specifically because there are at least 5-6 programs depending on what traffic you send and your own personal experience. I'd try a few and see what works for you.
As for squirting, I don't specifically know of a site that has that as a category, however I do know LiveJasmin and Imlive both have a few hosts that are actual squirters. You can link directly to their profiles.
