I'm guessing the issue is that you already have the PCB, which is why you can't just order one? I'd also guess the board to be just around 4" x 4" (based on hole spacing you specified), so any CNC mill should be able to handle this very easily. If it were me, I'd do it on my CNC mill, but you may be able to find a local machine shop with a CNC mill to do it for you. Cheers, -Neil.
