where does one start looking for such a service?
It isn't easy. I started by going to
http://local.google.com and running searches for "metal workers" and "metal fabricators" and "metal shops" and so forth. But that isn't where I eventually found the guy. I would call every single place I found on google and explain to them what I needed done ("I need a 24x18 inch sheet of aluminum bent in three places"). Most of them just told me they couldn't do it (it turned out most of the places I found make custom car parts). But I kept calling around. A few said they could do it if I didn't need it to be "precision," (if the angles could be a little off). A few said they could do it perfectly, but quoted a high price tag.
But some of the places that I called understood what I was looking for and referred me to other places. This is how I eventually found the guy who quoted me the great price. I just brought him in the panel I needed, and said "copy that." He was quick too -- I ordered two of them, and he had them 24 hours later. Cool guy, was very curious about what I was doing, so I explained it to him.
It wasn't an easy search, but it paid off in the end. I'm planning on getting several more panels made by the same guy.
