Wanted please A3 or A3 wide sub prints X12

[xXxCOZxXx]

Hi all. I need 12 prints doing as I don't have an A3 printer and it's for my dads friend so I said I would try to help. It's to be navy blue with 4 words in white (subtracted from the blue). Ideally on a wide format but if that's not possible I will just have to work in a white border. No huge issue.
Hoping somebody can help me
thanks

hi. can do A4 so probably no good. i could cut them in vinyl if needed.
