Where does one find turntable repair in Chicago ?

I wanted to change my cartridge,and I need to find a turntable repair place in Chicago. Since the turntable is 80 lbs., it would help if the company can do a home visit ! Anyone know a reliable firm ?

If you take your time, its not a difficult job at all. If you buy the cart from a good seller, they will usually have no problem walking you through the process if you have any trouble.
