Aerojet Services out of SDL is looking for Lear 35 FOs. Pay is very poor at $32K with a 14 on 7 off schedule. I have been told that they stay very busy and there is a short upgrade time. A LRJET type rating would ensure you'd never be unemployed for long.
Ameriflight has a PHX base and I hear they're desperate for PA-31 Pilots. That's also a very fast way to get Turbine PIC and upgrade to one of their turboprops.
Aerolynx has a night cargo operation out of FFZ in twin Cessnas. One of their job ads on
www.jsfirm.com said you could get six hours per night in a twin Cessna x5 days per week. Training is supposedly only a week long.

Rampart Aviation has some interesting turboprops, including the CA-212 out of MZJ and I think PHX now. Pay was $36K for FOs. 90%VFR skydive flying though. It's not the highest quality flight time but, it could bridge the gap to ATP minimums and get you to a regional if that's your goal.
Boutique Air may be looking for PC-12 FOs.
