I pull down 50 a year base salary with a 48 hour work week so I actually make pretty decent money as a Paramedic, especially with no state taxes. We get annual raises that bump you 2-3 k yearly until we top out at 63k a year. If you're an FTO and consistently have interns and new hires you can get close 70k/year without any OT but you'd have to have a new hire or intern on every one of your shifts and already be topped out on the pay scale. I work for a private agency contracted under a Public Utility Model.
But with that said, I like nice things so I work on cars on the side. Usually charge 20-30/hr (depending on if I like you or not) plus parts then just have my friend look up the time in AllData at his shop and bill it at that despite how long it takes me like any shop will do. I've had people :censored::censored::censored::censored::censored: and change their minds because it's "too expensive" only to come back in a day or two with the parts because they went to a shop and got quoted 3-4 times the hourly I quoted them. Just do simple stuff, brakes, oil changes, spark plugs. I don't really have the capabilities to do diagnostics beyond pulling codes and I don't do heavy line work, because I don't want to deal with dropping transmissions and what not on my days off in my driveway. At the house I grew up in we had a garage with an air system, BendPak 10k two post lift, a boat load of tools, it was the dream home garage. I miss it. I'd do pretty much anything when I lived there because I had the lift, a cherry picker, the air tools, a motor lift a transmission lift. All the goodies.
