Joe,
Check the Chamber of Commerce of Visitors Bureau in towns where you want to hunt, many of these groups in towns like Meeker, Craig, Steamboat Springs, and Kremmling have listing of active guides and outfitters and also ranches that permit hunting sometimes you can find cabins on the ranches. If you are thinking southwest Colorado look at Escalante Ranch near Delta, they have packages including use of a cabin, I believe the minimum group size is 4 hunters on the Escalante. If you are looking for elk meat the northwest area from Kremmling up through Steamboat Sprinhs, Hayden, Craig, and Meeker have had a number of leftover cow permits.
