Oh, also don't forget to check the enclosure manufacturers and their
distributors.  Most of them offer customization of their enclosures.
 Some will give you decent prices for machining holes in small
quantities if you are buying the enclosure from them also.  Electronic
Precepts is a distributor for Pac-Tec enclosures and they gave me a good
price for cutting holes in a few hundred boxes once.  Don't ask me how
much, that was years ago.  I seem to remember it being under five bucks
a piece for a few hundred.  Also check Simco, www.simcobox.com, for the
enclosures.  I have used them for years.  Never asked if they can
machine them though.
