I buy my bolt snaps from a guy on ebay. Without opening my account up to check I think his shop is called "Stainless Direct" or something like that. Search for stainless bolt snaps and he comes up, sells all sorts of stainless marine/chandlery stuff. The bolt snaps I use on my stages are about £2.95 each, I've had no corrosion problems with them at all and they always arrive within a couple of days.
For jubilee clips, I relocated a few from work years ago and still have enough
