One of the dealers that I visited in IL a couple of years ago had some bikes that had been custom painted by a shop in Kenosha, WI.
First class work IMHO!

 

Painted Horses in Alden, IL. Right near the IL/WI border.
Looks like a farm, but the barn has state-of-the-art paint booth inside.
Doug does great work. He painted my bagger.
