Mike, you'd have to elaborate a bit further.
Traditional, decorative chromium plating (such as that done for bumpers) IS done with an electro-plating method. They first, by electrolysis, deposit copper, then nickel (sometimes two separate nickel plates) and finally chromium. So when you say "electroplating" I'd like to know how what you describe differs from the traditional.
Note that the cost of traditional chrome plate has a lot to do with the hand labor and preparation, not the actual plating process itself. There is a lot of hand work involved in prep, and finally, in buffing at the end. Labor = $$$.
