I believe there's a guide on here that hosts hunters in G and H. I PMd him a few weeks ago but didn't get a response. So I'm not sure how active he is.
I think mntnguide would be able to point you in the right direction for what you're looking for. In the meantime, the Wyoming Outfitters & Guides Assoc. website has a new tool for searching for outfitters as shown here where you can click on "Find a Hunt or Activity" on top of the page and you can search for outfitters by region, species, etc.
