What do you want out of it? Organising an expedition to some remote part of the world isn't that hard but it does take time and effort. If you want a bit more civilisation head for nepal or south america, for a bit more independent look at central asia.
Two years ago we went to Kyrgyzstan, just the four of us. We hired a local company (ITMC) who sorted out the border permits and a driver whereas we did the rest with all the shopping, all the carrying and all the climbing ourselves. If you are self reliant I think you'll probably get more out of it. As a result of sponsorship and support form the MEF the price for the whole package came to about £800 per person including travel, food etc for a month which isn't bad. Doing it this way there guaranteed to be no hand holding.
