You can probably do a decent job yourself. Cut your body panel patterns out of stiff thick pattern paper. Get some dzus tools (dimpler and locator) from ********* or Aircraft Spruce. You might get lucky and find some partial sheets at a recycling facility.
If you need any help, take some pictures of your car to the airport and find some old fart (the best ones are sometimes grumpy - a total defense mechanism) with sheet metal machinery in his hangar and you might make a great new friend, who has fantastic stories (and some bad jokes.)
Oh yes, and he may just want to point that hotrod down the desert.....just don't put a lot of gas in it.
Have fun, make it an adventure, learn some more, you can do it.
