I'll add this from the auto restoration world.
We need skilled trimmers, chromers, porcelain coaters, woodgrainers, instrument repairmen, cloisonne emblem repairers, pick-and-file trim restoration guys and skilled radiator fabricators / repairmen.
Pick one of those, be the best at it and the industry will pay you whatever you want to charge.
I have two woodgrain guys I use. The last time I called one of them, he sounded so bad on the phone I thought he would drop dead in the middle of the call.
My instrument repair guy passed away last year, now I have to send them to another shop and get on the 6 month waiting list.
There are plenty of crappy autobody guys and lots of upholsterers who do a great job with boats and hotrods but a terrible job with proper, quality restoration work.
There's one radiator shop in the US and one in the UK that can build cellular, square tube, wire separated and honeycomb radiator cores. The last one we had built cost us $15,000.
There's two guys left doing porcelain work on engine componets, only one of them is any good.
Our chromer just shut down a couple months ago and we have to babysit the new guy. We hired their trim repair guy ourselves because we need the work done.
Figure out how to repair the enamel in cloisonne automotive badges and name your price.
Seriously. The average age of the guys doing this work is "dead". We're losing skilled people faster than anyone is able to learn this stuff.
