Homebrew PCBs

Hi All:
    I'm looking for a privateer or a company who can provide CNC-routed,
rather than etched, PCBs.
    I have to make up several one-off extender boards for doing repairs and
calibration on gear that uses motherboard back planes on card cages.
    So, in other words, I need boards that are complete no-brainers but
which can run, say, 15" long and I do need them cut to shape.
    Thanks . . . 

    Bill
