I laid out my gauge panel in CAD then had it laser cut out of 14ga stainless. I think that's the way to go. A lot of laser shops do government work cheap. This was $10 cash out the door and they completed it the afternoon I sent the file. If you've got a hand sketch of what you want for a panel I could create the dxf file for you. My gauges are just set in place in the pic but you'll get the idea.
