It's really no different than any other composite design and manufacture (carbon/epoxy). The cost of the carbon mat is higher but that's about it. Any glass shop can do what you need. It's carbon/carbon that needs specialty manufacturing and processing.
If all you're looking for is a part, then this is true, but if you want to see the carbon weave and/or actually need correct stiffness and strength in the needed places, this is way, way off. CF is NOT the same as fiberglass.
You have to specify the correct type of weave, thickness, lay it up in the correct pattern, cut the fabric in the correct shapes, have decent molds, mold release, and an autoclave if you really want good strength and stiffness. Should probably vacuum bag it at bare minimum.
You can't just blast fibers in a mold and sand it down to the appropriate size and shape, like you can with fiberglass. I'd find someone with CF experience and not be a guinea pig for someone who has done fiberglass and nothing else.
