Local manufacturing only works if you're in a place where there's a lot of manufacturing, or your product doesn't really require much manufacturing capability. You many need to be in a place where there's someone down the street with a 20 ton press. If you need a 20 ton press, you need to be in a place where at least three shops have one.
If you're making things which are basically PC boards, manufacturing is not too hard. Making boards and soldering parts onto them has a well developed workflow. There are lots of board houses and board-assembly services. If you design for what a pick and place machine can do easily, things usually go well. Hint: production is surface mount today. This is a pain for people who are used to prototyping with through-hole parts.
Kickstarter-class startups seem to have excessive problems with making cases and panels. Tooling for injection-moulded plastic is difficult and expensive. Once you get it right, the parts just fly out of the machines at a few cents per part. The production process is just getting warmed up on a run of 10,000 parts, and few Kickstarters get there. Basic truth about manufacturing: most of the processes are really cheap if you're making enough items, and far more expensive for short runs.
