Digital BW, The Print

Looking for some advice... To be considered for some exhibitions, I need to 
make slides of my black-and-white prints. I thought about sending the 
Photoshop files to the local photo lab for digital slide output but that seems 
expensive. Now I'm thinking of shooting the prints copystand-style on one roll 
of film and be done with it.

How do those on this list make slides of black and white Photoshop work?

If I do the copy stand method, what is a good slide film to use? I'd like to find a 
black and white slide film since I don't want color casts creeping in...any 
recommendations? Thanks in advance.
