I can't speak to those outfitters, but also consider llamas to get you back into the way-back.
Unless you don't have the gear necessary, it might be a viable option. llamas are very user friendly and easier than horses to tend, feed, water and lead.
Of course you want a comfy camp, but generally it is not really necessary to have a big wall tent, and such.
Being able to have heat though, (and this season was a perfect example of why) is very very nice and maybe even a make or break the trip detail in terms of enjoyment.
Oh, and NEVER, EVER hunt a mtn basin you have not glassed thoroughly first.
