Plenty of solutions there, I see. Heck the first one on the list has an 800 number! 800-341-1620
If the holes are standard size, you *could* get a single-hole puncher (they look a bit like a pair of pliers) and punch the holes manually; you'd need to mark the spots to be punched lightly with a pencil first, of course.
But you didn't mention how much paper you plan to punch. If it's a large volume, it would probably be a good idea to buy an A5 hole puncher, perhaps even an electric one.
