When I was building my Camaro I had a friend that did CAD design, there was a few custom parts we designed and had to get a machine shop involved to do the milling after we settled on something. One of the parts were radiator/fender supports. The going rate at that time was about $120 for a set of billet from 2 of the main stream and were rather plain looking, threw him a case of beer for the design and $20 for the machine work... In most of cases your paying for the machine and the knowledge to set it up.
