US-Based CNC Manufacturers

Do you have any recommendations for companies who offer services for large CNC projects? We are looking to get some molds for custom tanks and fiberglass boats fabricated. We already have the 3D STEP files created, just need the machining done.

Our largest dimensions are about 8ft W x 4ft H x 25ft L. The molds can be high density foam, or low density foam with a fiberglass shell or any similar material. We’ve received a couple quotes from CA companies for about $100k and it seems like there must be cheaper options especially if we have already completed the engineering. At this point it seems like we could get it fabricated anywhere and the shipping would still be cheaper.
