die casts for origami crease pattern?

Hi,

I want to score or "emboss" a crease pattern of an origami model on a sheet of paper. It will be done over 100 times so I need an efficient method of making the crease pattern. (A crease pattern is a bunch of lines where a person will fold the paper).

Is there a store that can do this? FedEx/Kinkos and Staples does not do it.

Someone suggested that I have a die cast in the shape of the crease pattern and then use this die to make the patterns. It would be like a cookie cutter where I go through and stamp the crease patterns on the paper. Where can I get a die cast?

Thanks,
