I do CV cuz the 800 lb gorilla custom installer in the area dosen't. I get clients that won't use him because they don't want to deal with multiple vendors.

I also make money on it and its easy to do.

I have CV companies here that are cheaper than I am but customers use me because I present myself as a professional, same reason they use me instead of Sears for custom install, its not all about price. I do a better job and am more knowlegeable.
