Looking for laser pinholes

I'm building a "stereo" pinhole camera for pinhole day. I'm using a Polaroid
Portrait camera (anyone know how to get the "faceplate" off of it?). While I
usually build my own, this project requires two identical pinholes.

So, I tried contacting Guillermo Penate, but the email address and web pages
I have aren't working (are you out there Guillermo?).

If anyone can point me to a source (reasonably priced, I looked at Edmund
Scientific and they want ~$50 each!) I'd appreciate it. I need a diameter of
.5mm (focal length is about 120mm, I've done some of the calculations
available on the net and they take me to around .4 to .5, f222 to
f3somethingoranother).

And if anyone can point me to a source of reasonably priced polaroid film
for the 4X5 film holders that would be nice too, that stuff is expensive!
