The last time I had decals made for a bike I used an online place called Sticky Life (https://www.stickylife.com). Turned out pretty good. But more recently…when the topic of custom decals has come up on these forums…others have suggested printing them DIY on clear adhesive film available at office supply stores (not sure if that requires special ink). Perhaps you could take the graphic to the office supply store on a USB thumb drive and print it there????
