If you're looking at basic glider pilot training, probably a copy of the BGA Instructor manual might be enough. Moving to Iran (or anywhere) just to bash circuits doesn't sound very enticing, so I doubt you'd get much help from established instructors unless they have some other reason for wanting to be in Iran.
If you're looking at a starting a base to fly in the mountains, however, I think an advert on gliderpilot.net might find you more than one instructor who wants to spend some time doing this. With a good enough fleet (and subject to the political situation) I'd think there are quite a few tourist pilots who have "done" the Alps and are looking for a new challenge.
Two main problems occur to me:
1. Will the Iranian military let pilots fly where they want to? Glider pilots tend to be somewhat anti-authority.
2. No beer? This could be fatal to any tourist market.
