The best bet for us is to do it manually. Buy hole punches in the sizes you need, 1/8" for snaps, 3/16", 1/4", etc. for grommets. Then get your dies and setting tools as req'd. I highly recommend getting a rawhide mallet for setting. Regular hammers mushroom and crack your setting tools. Para-gear.com is a good source for this stuff if you don't have anything local. Try to set your hardware in webbing if possible. Acts as a doubler and less likely to tear out. Funny thing is, I've worked on those big pneumatic machines w/ auto feed and while you can can set a buttload of hardware, they were very twitchy and prone to break down or jam.
