Is there anyone out there that stocks vinyl insignia in a variety of nations and sizes?

Alternately, is there anyone out there with cut files for a variety of nations?

I found it hard to order insignia for my Ringmaster.  Everything was either out of stock, came from China, or was the wrong size.  I ended up cutting a (not terribly good) US Navy insignia by hand from some scrap vinyl.

Being able to order something, or to give a cut file with some sweet-talking to my vinyl-cutting club-member, would be nice.

Have you tried Charles of CFC Graphics.   For US markings I got mine from Brodak ans I think SIG has some too.

Brodak.  Of course.  It looks like all they have is one style, though.

It looks like everything Sig has is waterslide.  I have nothing against that in principle, but I kinda like 'coat for casual building.

Charles is my backup if I can't get stuff locally -- the local guy is eager to help, though.

I've been getting custom-made stuff from a local shop called Pit Stop Graphics. 
They are vinyl spray paint masks. 
With my help they have developed modern USAF roundels, "USAF" and "U.S. AIR FORCE".
