Look for any and all of the sponsors/people who work with the Battlebots groups. While some of them are big names (Solidworks) you will also find lots of little guys flagged in there who are doing the contract manufacturing. But, it won't be $100 like China. Expect minimum NRE of about $5K to make it worthwhile to them. And, please understand that, even so, you are still an unprofitable nuisance--so be SUPER polite when dealing with them. Also please understand that the manufacturer talking to you is at the top of a pyramid of problems being caused by your choices, part manufacturers, material suppliers, etc.--their bad day is generally due to everybody else (including you!) However, since you are dealing with real people face to face and being really nice, you will find that they often will go an extra mile for you that you would never get otherwise. (One shop I worked with had yield problems on assembling a board. It turned out the big manufacturer created a really brain damaged part whose footprint just sucked terribly--it was so bad that they quickly EOLd the part and changed the footprint. We had ordered 100 boards expecting that we needed 50 with lots of lead. Of course, that wasn't happening. One worker there sat down, hand tinned an almost microscopic chip 100+ times and resoldered those chips repeatedly until we had fifty. Needless to say, I funnelled any and all business I could through them from that point forward.) Any company willing to deal with you at low volumes should be treated like you have found gold nuggets--because you have.
