Depending on what you are making, a local manufacturing job shop or small scale contract manufacturer may be the way to go. 15 years ago during/right out of college, I worked as the software dev/IT department for a company in Central Kansas (http://www.grainbeltsupply.com/ http://www.grainbeltsupply.com/) that would be an ideal partner for you on something like this. I don't know where you are, if they still would be (live in different state, haven't talked to anyone there in about a decade), etc, but everything you are describing sounds like the kind of thing a job shop like GBS would be helpful for manufacturing the kinds of small scale production you seem to be talking about. Searching for "fabrication job shop" with your city/region should get you a number of google hits for places that would be helpful. Speaking solely from what I have observed being on the IT side of two manufacturing companies, your budget for machinery investment is probably an order of magnitude low. Probably want a partner to start.
