Rhm9,
Take it easy, hoss. People are not always going to make the right choice on anything. If you're in it for the long haul, you can sit back and laugh at some of these jobs you don't get. One of the best referrals I ever got was from a homebuyer that went with "the other guy". Regarding the Training Dept., you should be happy they are selling a DIY video. The average homeowner will see this, realize how much time and tools it takes, and call you anyway. Either that or they will totally botch it and call you to fix. (You charge more to fix, right?)
