South Fork Outfitters. Great guides and people. You'll float the most scenic stretch of river and catch lots of fish during that time of year. Here is their link: http://southforkoutfitters.com/ they have some world-class guides.
Then there is the best fly shop in the world located in Idaho Falls, Idaho - Jimmy's All Season Angler: http://jimmysflyshop.com/
The link to Bruce Staples' book mentioned above gives some great info (http://www.flyanglersonline.com/feat...trivers/snake/) Bruce is a great friend and mentor. He works at Jimmy's Fly Shop once a week and would gladly answer any questions you or your boss may have.
Beginning around the last week of June - first week of July the Salmonfly hatch kicks into gear on the river and you could catch a fish of a lifetime.
Good luck in your search.
Kelly.

"There will be days when the fishing is better than one's most optimistic forecast, others when it is far worse. Either is a gain over just staying home."
