I manage a shop in OKC and we do tons of expeditor work in fact its prob 90% of our business so Ive done cable door lock installs many many times, I kinda just developed my own setup using standard DEI Actuators and speed clips to hold the cable. As for pricing I charge $75 per door to the dealer plus $100 for wiring and a single switch in the driver door or add an additional $129 for keyless/$199 for alarm. I mainly do the Toyota's with cable locks and I can usually get a 4 door car with one switch in the drivers door and keyless entry in about 3-4 hrs.
