Clay, I might not be on the same track here, but isnt the template what you take to the print shop? You create it out of something, like plastic, or paper, or?
depends on how you want to get them done pretty much most place will allow you to just come up with your design as you like in jpg or psd or pdf format. If you have it printed at an ordinary sort of place they will likely print it onto either an A3 or A4 press so you just need to keep it ot one of those sizes, best thing to do is speak to the place first
