AS Symbol ES 2009 rear resin decal

Hi all,
The rear of my 2009 Symbol has problems with paint peeling off above the glass on both rear doors of my Peugeot Boxer. This area will need to be re-sprayed. On contacting Auto-sleeper they said they generally don't hold a stock of parts beyond 10 years so could only offer a resin decal which is the right size but the wrong colour combination, or a longer decal in a different font to mine. Local printer companies don't do resin vehicle signs. 
Has anyone out there had a similar experience and found a solution/company to produce a copy? 
Many thanks in anticipation!
