agreed... and no, I wouldn't build the bard like put up the walls and frame, I agree, it was worth paying, but out sourcing the gravel install, put in your own insulation, install your garage door and openers, run your own electric... that stuff is not bad, take your time and it will be fine. also get some drywall or plywood or something on the ceiling to help trap the cool in the summer and heat in the winter or everything will blow right out making it impossible to get to hold a temperature except extremes.
