Ben,
There are several outfitters here in our area that are affiliated with the Cableas team. As near as I know, they are all solid guys with ethics and good reputations. I've never been on one of their hunts, but the outfitters I know who work with Cabelas are all solid. I know one of the guys at Cabelas and he's honest and above board.
You'll pay a bit more for the hunt through Cabelas, but I think they do their homeowrk.
