8mm prints are, to my knowledge, not possible anywhere these days. 16mm blow ups are possible but not costs effective unless you specifically want that 'look'.
Equipment is very cheap.
Some of it very good, all of it very old. Good luck, I've been thinking about playing around with Regular 8mm because it seems you can fit four frames into one projected 16mm frame. Although I'm sure that 'experiment' has been done to death many years ago.
