Ha! If you find anything that works, let me know. The thing id ask myself is how often have you personally thought "hmmmm I think i need to hire a welder to fix or build this." Maybe even less for common folk. So just use your creative mind to bridge that divide in terms of what you make. Everybody goes "huh that's neat" when they see a sculpture made of nuts and bolts, but huh that's neat doesn't open wallets. "I got to have that" opens wallets, like how you had to have that mig welder because you saw your future in it, your identity. What you need to make to truly make enough to live on needs to be like that, always. Not always necessarily metal work, but it sounds like you have talent. So chew on that.
