Looking to hire someone to install insulation

I found a company that does blown cellulose. I read up on cellulose and decided to give it a try. The difference was huge. My wife started to complain that the house is too hot.

I was charged about $1400 to do 1 bedroom and 2 large walls in the living room. The only negative is that I had to patch up the holes when they were done. They drilled 2 inch holes about 18 inches apart on the bottom and the top of the wall.
