Literally 5 minutes from my place. I'm going to take the coin toss assembly and the habitrail to these guys for a quote.
Nino, make sure they dont chrome the parts then paint over with gold paint then clearcoat. It looks amnazing but wears off real easy. Thats what most places do.
You will find out real quick that "gold" finishing is alot more painfull and complex than any other dam finish.
I am looking forward to see what these guys suggest. Gold is always more expensive because hardly anyone gets things done in gold, unlike chrome which lasts forever.
Dont forget before and after photos please. 
Thanks for the tip, Brett. I'm hoping they are open tomorrow or Monday. I'll ask about "real" gold plating. The buyer has requested this game to be "collector's quality". No expense will be spared
