BZNSRAT - I believe it would be more prudent for you to build your own. Dave is right; why pay for someone else's labor just to cut it up. Do what Don told 1940tipster; mock your parts up in position, move them around, etc. Then take measurements and build it. I find that graph paper is handy for sketching things to scale and transferring measurements. I sometimes transfer the diagram, full size, to my garage floor to use as a guide (see the coupe build pics in my gallery).

If you aren't confident with your fabricating skills, cut and tack the pieces together and take them to a competent welder.
