Dont do it for track homes, the electricians usually do it for free and use those stupid radio shack screw on connectors or use 9's or teeth to crimp the fitting. Better money is with phone/data, speaker systems. Expand in the forementioned and find a custom home builder and buy him a beer to sell your service. Mention cash and kickback and you may get in the door. Your custom dude isnt going to do it for free.
