You can also easily do the blown insulation yourself. When you buy like 20 bags from HD, let you use machine for free. Should cost about 200 for the bags. Just need to find a friend/wife/husband, who will help ya out for a few hours. Buy the full body suits, and two sets of goggles, gloves, and face masks, and total cost is about $250. Super easy, we did it at my dads house, and are going to do my Petworth rowhouse shortly.
