how much does it cost to get things black chrome plated?

 

whjat do yopu want it for ... low light reflection capabilities or good looks?
I'd say you have to google around and ask the providers
http://www.anoplate.com do black chrome plating but I'm sure there's some in your area as well

 

If you want to find someone in your area , simply find any shop that build motorcycles (choppers , etc.) they always have plenty of contacts for chroming places and they usually chrome stuff in different colors as well .(that's what i did and it worked for me)

 

Why not powder coat them black or see if they have a black chrome looking powder coating.
