Email local companies

I have been thinking about Emailing all the local AC/Heat companies around my area.

It seems they all have someone buying there takeouts, but I think I can pay a little more then others for the units. I say this because I strip them down beyond what I see others turning in. They sell the motors as motors and compressors for dirt cheap instead of cleaning them of there wonderful copper. I take anything with a coil and clean it. This includes even the small relays on the circuit boards get cleaned of there copper.
