Well let me throw in my 2cents here. That 9 TV locations is gonna come back to haunt you. I almost exclusively do new homes and most are at least that size and much larger. I sell all those extra locations even if they say they are not going to use them and I have never had a customer complain yet because it actually only makes sense. As far as taking on extras that I am not trained for I just don't do it as a habit and if I do I call and expert for the customer. It doesn't dent my ego to admit I am not an expert and plus I don't have the headache I would have if I did do it!
