I dont know if you have checked into them, but last I knew Desert Ambulance operated in Barstow, they hold the 911 contract for the city. I know at one time they operated 3 units a shift and the shifts were 48 on 48 off. Pay was decent from what i know of. down side is that they are a family owned company. The father started the company, the son is the manager and the daughter was a basic on one of the crews. Other than that the company was a decent place to work for. I worked as a dispatcher for them for about 6 months or so before I was let go. I was young, dumb, and didnt want to take advice from anybody on how to do my job, so they let me go. All the information that I gave is about 11 years old. I worked for them when I was 19, back in 2002.
