Powder Coating deal question

[deicustoms1]

I just bought a 2nd set of stock rims(5) to get powder coated.

Contacted A M Metal Finishing, (www.ammetal.com)

They say "To bead blast them then pretreat them then apply the powder would be $100 .00 a wheel. That includes the powder, takes 4-5 days"

First, what do you think of that price, is it average? Second, is that all there is to it, or will I need any additional work done on them? And does the company look good from what you can tell?

thanks
