Bill's right practice on your own,impress him with what youve done he,s probally not going to be impressed by what you want to do.I work at Colonial chevrolet in virginia and i have 2 helpers ,they have been with me for about a year and there just getting into repairing very small dings.Working on comission and not being sure of what your doing is a good way to starve.I ve been doing it for 28 years and well into the 6 figures,And it does take a long time to be good...HINT bodywork is a lot mental,you gotta be tuff and ride it out.
