Hello, There are a lot of companies out there. I'll list my favorites: Photo Sciences www.photo-sciences.com Their phone number in CA: 310-784-7460 Another company with a very quick turn-around time is Microtronics www.microtronicsinc.com They're located in PA. Phone number there: 215-968-5058 The third one would be LSI Photomoask www.lsiphotomask.com. Phone number in AZ: 480-545-4545 There are many more companies, but these three should do the job you're interested in.
