Depends on how handy you or your dad are and what tools you already have. Have him take a look at the link and go from there. There are basic prices there for you. Your first task will be the finding availability of the rock wool or OC 703 in your area. 8 lb rock wool is cheaper but works just as well. Shipping costs more than the material itself. Google insulation suppliers in your area to find it. Home improvement stores will not have this.
