If you really want to do it, then I suggest you contact Derby Plating Services. They don't deal with industrial huge plating and have a great reputation amongst the classic car crowd.
Another vote for Derby Plating from me, did a superb job on some rare & delicate parts for me
I suspect they may turn you down, as they won't risk their reputation & just plate 'anything' and fully assembled wheels may be a no, (they won't do Mog 'screen pillars, as they feel chrome will eventually flake off due to the poor base metal MMC use)
