PPO work here in Texas seems limited and the money obviously isnt as good as what you're making as a BW contractor. im at BW right now and there are a few guys who are in the class with me as BW contractors. you aren't going to find anything that pays as much here.
PSD work stateside, and especially in Texas, is hard to come by. some it seems to be short term, 1 week or less, and sporadic. alot of off-duty cops are also in the PSD game even though most aren't trained to do PSD work and on top of that have no insurance in case something goes sideways and someone tries to sue them. obviously their department will not accept culpability for off-duty employment.
personally, being in the Exec Protection school here at BW right now (last day is today) after seeing all the info they gave us, there is no way an untrained police officer would be able to know all of this. 90% of this information was not part of police academy. about 10% was: night shooting, room clearing, are the two i can think of off hand.
things like: ambush/counterambush, surveillance/countersurveillance, attack-on-principal, cover/evacuate, motorcade driving, route planning, advance, "last-man standing" drill, formations (simple diamond, diamond, extended "iraqi" diamond, etc), comms, etc, most cops working PSD as an off-duty gig have little to no training in regards to this stuff.
yesterday we did force-on-force/counterambush/cover-evac drills with simunitions and flash-bangs. i don't know of any police academy teaching this!
anyway if you are looking for consistent work with good $$$ i'd ask BW for another contract.
