You could set them up in a word processor, take the file down to a copy/print shop or sign shop and have them print them out for you. You could even space them out on one sheet so it would be a simple install. If you printed them on a piece of acetate like used for a transparency you could just glue or tape it down (this would be inexpensive).
Bobby's decals worked really well and you could surely duplicate that at a sign shop. Might cost you more but they do look good.
