"He who marches out of step hears another drum." ~ Ken Kesey
What is your concern with outsourcing?.....Turn around time?....Costs?.....Many suppliers print bumper stickers with HP Indigo Presses and buy material in mass quantities....So quite often you can buy the finished product for the same or less than doing it your self.....I use www.stickerman.com www.tradenetcatalog.com or www.stouse.com
