Looking for a way to combine my job with my love of cars, any ideas?

Yeah, I'm kind of looking for a full time gig, freelance is never good for me.

I was thinking of trying to ride the fame of one of those Discovery shows like Vegas Rat Rod or Fast and Loud.

But I'm sure they already have a fully staffed team.

I'm sure they do at the moment also, but they got them from somewhere didn't they? :D

Someone mentioned the other day trying to find a place that will let me do web design full time and let me apprentice in some type of repair for free, like body work or paint

My first thought was paint, since you have some experience in design already.
Also, decent painters are not easy to find and make pretty good money.
Don't get me wrong as painting isn't all that easy, but it's a LOT less physical work than a lot of other things we do to pay the bills.
Body work would suck IMO, but painters don't generally do body work. (they just ***** about it) :D
I worked in the body and paint shop at a Ford dealership in CA and got some experience in it, but only do it for my own benefit.

My neighbor found out I have the tools and a mig welder so he always asks if I will do some work for him. (but I won't do it)
I offer to show him the basics, and even to loan him the tools but I have zero interest in actually doing it for him.
