Good luck with your career change, I have faith in you!
A friend of mine down here bought a laser engraver after he got laid off, that was 9 years ago, he's cranking out trophies, name tags and personalized yeti. I don't know how great of living he's making off it but he has a store front now and a few employees, so it's not too bad.
I left IBM 10 years ago to become handyman. Now I'm a master handyman with an apprentice, who's now capable of running most jobs himself.
