Not sure if you got this squared away Kevin, but I am currently using Precision Powder Coat in Crystal Lake (hour from Chicago). Bob is a great dude with a professional shop and knows how to work on bike parts. He has plugs/caps/blocks galore, so you don't have to worry about doing the prep work, and he knows what parts should NOT be painted/coated.
I have not received my parts back yet, but his quoted price was very fair.
