Scan the artwork, find someone who knows how to use Corel Draw or something similar, do your own sets.
OR
you can do what i did. I told a melbourne supplier who has a printer that I was about to start selling both Black Knight 2000 and No Fear decals on ebay for $299.
Within a few weeks, he was selling perfectly printed quality decal sets for $249.00 for both BK2000 and No Fear which had never been available anywhere before.
I will tell him I am about to do Terminator 2, Dr Who and ten others that are not available. Theres more than one way to skin a cat.lol
