Cadmium plating was heavily restricted with the acceptance of Directive 2002/95/EC (also called RoHS-1). There are still some companies "grandfathered" but that number diminishes each year. Most shops are restricting the process to only military and aerospace applications now.
That being said, I have been using Chem Processing for my cad plating needs.

If the part does not absolutely have to be Cad, then I usually opt for a zinc plating from RMF. RMF also offers several other processes that are widely used in automotive manufacturing.
