In reply to andrewm1000:
Have a word with Alan Curr at Wild Frontiers 020 7736 3968. They organised the trek I did up the Wakhan last year. He will be able to tell you who to contact in Ishkashim and who not to go with. Yar Mohammad was one of our guides and if you can find the famous Amin Beg you will have one of the regions hardest workers on your team.

Get a copy of Peaks of Silver and Jade by Pinelli which gives a good set of mountaineering routes you can do from the Wakhan.
