Rocky Mountain Roosters is who I have used for the past few years. Fair piece for you since it is down in Calhan but excellent bird hunting. Price is $200 per gun for the four hour hunt and they provide a guide and dogs. Expect to tip the guide as well. If you have dogs, you can run yours instead. I think I enjoy watching the guides working their dogs more than taking a pheasant, chukar or quail.

They will put you on some birds, but these aren't domesticated. They will make you work and the bastards will run more than flush if it wasn't for the dogs.
