I do not have any personal experiences to share as I have never gone on a guided hunt. However, if I was in your position and did not know where to start then I would probably look at US Outfitters via Cabelas...if I remember correctly. I have heard quite a few good things about them and continue to see their endorsements on a variety of the televised hunting programs.

Maybe one of the others can provide more specific info on other reputable outfitters.
