Need a 12x12 steel electrical box panel punched for 8 xlr connectors, looking to find shops that do that sort of work nicely.
If you're comfortable doing it yourself, a drill with a few bits, a caliper, a center punch, and a knockout punch is all it takes. Well, the caliper isn't completely necessary, but I'd recommend one if you're going to be measuring all that stuff.
In lieu of a caliper, you can also print out the layout onto a sheet of paper or label material (in scale, of course), center punch through that onto the panel, and you won't have to do so much measuring. This method is my preference.
Brother P-Touch labels work well for labelling.
to add to above, a step bit instead of a punch can be a cheaper alternative...
