The sizing and placement of custom etching would be just one more thing that someone would have a probelm with. Who would pick those parameters?
Unless you wanted to be very specific about test run burns, approval of final designs, etc.. You could chew

I'm not sure everyone realizes what time cost on some of the laser and milling machines.
If you've never dealt with it, why would you?
Casey's gonna pull her hair out one of these days and it's not going to grow back.
You better think about it.. LOL
It is a great idea by the way but you'd have to be very specific in the contracting of the work.
