Cardee-
You may want to call Kinkos....or other printing/copy shops in your area. A lot of places are getting large format ink jet printers, and depending on your budget, can print them quite reasonably.
OR...
You can purchase a roll of yellow art paper, and print out your lettering, either at home, or have Kinkos print laser copies. Then just cut out eash letter, and glue to the yellow paper, then take it to be laminated! Lamination will make it water proof, and I suggest requesting at LEAST 2" of extra lamintaion on each end so you can fold it over (to make 1" border) and cut a hole thru both pieces so you can tie it to a fence. If you print the letters yourself, you can use red letters for the "caution" and black for the rest.
Call around and check laminating prices, and also size limitations....length usually isnt an issue, but the width can be. You can also check with the school.....some schools have the equiptment. Its been awhile since i was in school, but the high school I went to would allow the use of our laminator for school related stuff for pennies a square inch.
They may also have the paper.....or check out
****Blick.com
they have 24" x 60' rolls of colored art paper for $11.25.
Just some ideas!
