Hmm, really not prepared to price it out for you, but Please try to buy a mountain top, haul utilities 500 yards or more, then blast the solid rock top off the mountain, and create a 1 acre pad, then get all the permits and after all that find a contractor (looking probably at 300 to 400K just to get that far, then find someone to build you a just plain home for less than 200 sqf.
