I have FomaPan R100 reversal stock, from J&C.
Wal Mart says that they don't do anything other than "regular film". I at least think that that's what they said, as I couldn't understand anything the lady said in horrible English. They said "we run slide", which I'm assuming means that they do 35mm slides, but that's obviously not what I want. And can you believe that they charge 60 cents per slide.
So I don't think that they even send out movies. I'll have to find another place. And as to slitting the film, I can build a film slitter, no big deal.
How are you processing (or going to process) your own film?
