I don't know if you are set on Montana but it's neighbor to the east, North Dakota, is booming in the oil and gas industry and since many unemployed here went there to work there has not been much in the way of homes or apartments to stay in so a lot of construction in that area is happening. I believe most of the work is in western ND which wouldn't be far from MT border.
What is your pilot license? Rotorwing or fixed wing? I read there is a shortage of rotorwing pilots, many needed for offshore drilling shuttles. If it's fixed wing Alaska could always use some good "bush" pilots and they are very gun friendly there. I think with a commercial pilot's license you would have many opportunities available. Maybe you could work for the state police in Montana as a pilot.
