George,
I'd open the yellow pages and look under Automobiles, racing and sports cars to find a fabricator. Look for a shop that does street rods or performance work. As large as Hotlanta is there must be one close, if not I know of one just north of you over the SC border on I-85 near Greenville. Ask around at any speed shops or engine builders as they usually know/deal with them.
That is also a good way to check their references before committing $$ to them.
Good luck,
Tobias MB
