I its probably kinda far for you, but S.G. Torrice in Woburn/Wilmington is always hiring for work in the sheetmetal shop and on the store side. It may not be what you are looking for, but if you can find a better place to find a job than a supply house you'd allready have another gig. A couple people I went to school with started working there and they had all sorts of contacts for a job by the time they got outta school. Even if you dont go to that one, try some supply shops near your area, even if it isnt the pay you want, you'll be able to pick peoples brains while there, and they may let you take the classes and certification tests that they hold there. Could be a good way to get your foot in the door.
Food for thought.
