[sdiy] Custom Membrane Panels?

[MTG]

I need to make a low volume (less than 100, maybe a lot less) panel for 
a project.  Not the actual panel, a thing that sticks on it. But thicker 
than a sticker/decal.  There are no switches on the panel, but it will 
have a see-through part for 7-segment LEDs and some text.  That's it.  
This is a bit smaller than a business card overall. Anyone have any 
sources they can recommend?  I mean, I can upload gerbers and get 
boards, upload STLs and get plastic stuff. Is there such a place for 
panel graphics?

Even help with the terminology would be great at this point.

Thanks,
GB
