Hey there, I am not in the fox valley area but I manage a metal finishing company in Butler WI called Efco Finishing we can sand blast paint and or powder coat wheels let me know if you are interested our number is 262 781 4411 ask for Jon.
If you want them powder coated I can do gloss black for about $75.00/wheel if you just wanted them spray painted I can do them for around $50.00/wheel. What type of wheels are they? Stock Aluminum or steel wheels? Also just and FYI I would need you to bring them here and pick them up.
