Hi Cinqster!
I don't know where are you living, and if you are in hurry, but we have a laser engraving machine at work.
I think it would be powerfull enough to make little holes in a thin piece of leather (btw, I live in France).
MP-me if you are interested, It'd be free excepted for shipping fees.
Hope to see more updates in the near future.
Olivier.
