Search the net on 'Boat Names'. You'll find companies that produce decals for stick on names, images and striping. I used:
http://www.boatnames.com.au/ to produce my boat name and rego stickers. They did a good job and provided easy to follow instructions.
If you don't want to buy from Australia, I am sure that there are many companies in the USA that offer the same service.
Good Luck!
