Anybody able to recommend a USA company that can do automated panel

Thanks!
Thanks to Billy for recommending SendCutSend https://sendcutsend.com/
in Reno, NV - ridiculously inexpensive and very high quality from
Billy's experience.

When it comes time, what I'll do is:
1) get a steel template laser cut by these guys (from my DXF)
2) clamp it to the panel and use it as a guide to
drill all the mounting holes in a drill press.
3) remove the template, then reattach with stand-offs
4) use a small router to cut the instrument holes

Hope that helps someone, and thanks again Billy!
I'm going to chuckle all day about this one. Nice finesse by the laser shop. Possibly brilliant. They get some work, maybe open a new market, don't have to screw around with a customer's easily trashed part.

I would use sanding drums in the drill press rather than a router. Something fairly big (1/4 hole dia or larger). Clamp the guide flush for that and remove most material with a hole saw, then finish with sanding drum. Start with a fairly low speed (it won't take a lot of speed).

I use a CAD plotted paper template secured to the panel with double stick tape. Then a drill press for mounting holes and creation of rough openings to within about 1/16 inch. Finish off with 1-1/2 diameter drum sander to bring to the line. Normally only a small amount of hand work to refine to finished.
It takes an afternoon to do a glass panel. There are also punches available for the common instrument sizes. They are fairly expensive but much less so than making so do it yourself CAM system. For aluminum punching is much less tedious.

Anyone try an instrument hole thrust punch? https://www.aircraftspruce.com/catal...ts123chole.php Surprised no one has brought it up yet. And has anyone used one of these on fiberglass and how did it go?

I have tried punches like that on a fiberglass panel when making a new panel recently for my DG300. Tested a 57mm punch (a Greenleee punch, not the one from ATS) and, while it was able to cut a hole, it was very difficult and risked cracking the panel. I ultimately use hole saws and a little hand sanding to finish the edges with good results.
