well...first it's JBJ not JBL.

Uhh...there is no industry standard for installation as there are too many variables. Charge what you can...whatever the market will bear. Of course there is a limit to that last statement. You don't want to price yourself out of the project.

I think you might have of missed my point of getting some professional training...not just for wiring etc. but for creating proposals and management of your AV firm.

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!
