Looking to Expand Company

Hi everyone, our company does lots of machining work (machine shop) we are based in Silicon Valley and have ITAR, ISO 9001, and 13485. In terms of capabilities we have 30 CNC milling machines including 5-axis, horizontals, and verticals. We also utilize about 25 CNC lathes. Everything else is usually an OSP (heat treats, welding, etching, etc.). With this in mind (location and high production costs) we are trying to find a new product to develop for ourselves and expand out. Any advice or plausible ideas that anyone would be willing to share?
