Sorry no direct links but the printers I used had been Lancashire based:~
No real problems in tracking these sort of suppliers down though- the same company did some decals for the old type of petrol cans.
The Volvo vinyl is exterior grade but the printer should advise on this etc.
From memory you may find these suppliers on ebay.
https://www.davebarton.com/ is an interesting site but the post charges are daft now.
Hope you get it sorted.
Bob.
