Welcome to the new and improved Proflex / K2 Tech Forum!
I worked at a Sign design agency that was very capable to provide sticker sets. Unfortunately this means I cannot help you personally but I am sure what martin suggested is a good way. Be sure to show up prepared if you go to a busy sign company for the stickers. It was very easy to neglect these small jobs for those who came in wanting such done. Provide a well lit high resolution image on compact disc preferably flat (not on the bike), Provide a note with the CD telling quantity and size for all the logos it contains. They will probably give you a reasonable price if they see everything is organized and ready to print.It is sometimes possible to print on clear vinyl depending on the machine they are using. Clear vinyl will provide a professional stock look.If you ask for an uncut version they might give it to you for even less but you will be responsible for cutting it yourself.Good luck.
