Hi,

i dunno where you're located and how much money you'd like to shell out, but i 
can tell what we used at my former employers. We used Nickel/Gold plated 
aluminium housings for broadband rf stuff and usually we had those cases made 
by either TWM (?) in UK or KMCO in Japan. Funny thing is, that KMCO nearly 
always was cheaper, quicker and higher in quality both of the milling as well 
as the gold plating, even though delivery was to Germany...
But i don't know whether or not hey would offer the gold plating on its own.

HTH,
Florian
