Anybody engraving aluminum?

Looking for a supplier of engraved aluminum plates. This is for a
gift. My friend made a camper top from aluminum plate, and This would
be like a manufacturers plate on it.

1/8 by 3 x 5 inches aluminum plate with some lettering.

Can anyone suggest a supplier? Contact me offsite at lwgran@...
and I'll send you a pdf or doc file showing the letters.

The supplier would have to go from .doc to gcode, and then cut it out.
I'm looking for a carved effect on the letters, so maybe plate is
thicker than 1/8"?

Thanks, Larry Gran
