Hi Jim, Based upon the information you gave it sounds like Power Circuits would be a good fit. They have small lot processing and they build microvia boards in as little as 3 days. Call Larry Benton (714-241-0303) with any questions you have. He is great help during the design phase. Best regards, Keith Larson Circuit Technology Inc.
