ok, i assumed you listing "POST" meant you had a basic POST certificate. an academy graduation certificate isn't the same since you don't work for an agency thus you don't have a POST certificate (basic, intermediate, advanced, etc)
nothing against you at all. i have seen alot of guys (police and military types) looking for local EP work, some have experience and/or training, and some do not.
i know a guy who claimed to be a former Army Ranger (who really wasnt) and said he was some black belt in martial arts. he said he wanted to be a bodyguard and was looking for someone to pay his way to attend ESI. to this day i dont think he's found a "sponsor."
there are alot of people who want to do EP work since it pays fairly well, but it is a hard niche to get into. most people who need protection don't want to pay for it, and the ones who do pay for it have guys that are dug in like ticks. if you are doing stateside EP work it is generally not enough for full time work.
in austin i know a group that does part time (on-call) EP gigs, they are not regular and i'd say about less than 1 a month. they are trying to get their name out, so on occasion, they will even do some pro-bono movements with major celebrities, even though there really is no specific threat. kinda sucks doing it for free since you are essentially taking on a risk for nothing, not to mention the time and cost of doing business (gasoline if you're driving miss daisy around, etc).
good luck in your search, i hope you can find something. but will all the off-duty cops who can carry weapons (legally) and former federal agents with an EP background it is hard to find consistent work.
also, keep in mind insurance and liability issues. some off duty cops working EP gigs as overtime have little to no EP experience, can't afford or wont pay for the training, and almost none of them carry liability insurance.
my friend's outfit carries $2 million in liability insurance just in case....most cops i know dont have any liability insurance.
