Cadmium Plating is still commonly used in the aircraft industry as a protective coating. A good electroplater will have access to this.
You will find most industrial plating places & hardchrome platers can Cad. Plate. Hardchrome is the kind you see on shock absorber shafts, hydraulic actuators and the like.
Cad plating is muuuuch cheaper than chrome plating.(Not much on a CMP chromed except the wiper arm knob
) Remember to wash you hands if you have touched cadmium plating. It is toxic, and the oxide (looks like salt) is highly toxic.
