Price to buy fabricated car body replica and process

Hi,

I have 2 questions.

How much would it cost to order a replica car body and frame in order to restore a classic car?
The car I like is hard to find and expensive.

What is the process of fabricating a car body replica?
Type of metal, materials, tools, types of welding?

Car: AMX Javelin

I am thinking of learning how to do this as a career.
I already know some auto repair but I am not a licensed mechanic because it takes 4 years apprenticeship and I dont want to go back to college again after my business degree.
I cant find a job with a business degree so I sm exploring other opportunities. Oh and my dad was/is a master mechanic but I taught myself.

Hey! Did you find your AMX Javelin? If I can help with any difficult to find parts, please let me know. We can 3D print classic car parts --plastics, composites, and most types of metal.
