Electroplating stainless is a bit tricky, because what makes stainless steel "stainless" is the oxide layer it forms over itself that prevents corrosion ("staining"). This same oxide layer makes it difficult to plate the part and obtain good adhesion of the plated layer.
This is due to the chromium content alloyed into the steel. Poor preparation of the surface will mean blistering and peeling of the plated layer(s).
There are any number of shops that can do it, though you will pay for their expertise.
I can refer you to a good shop if interested. I was a plating engineer for 36 years, just retired.
No, I can't get any side jobs done at my old job, sorry! If I could, I'd have a bunch of Oldsmobile parts over there!
