We organised a group of 6 of us from Singapore, Korea and Hong Kong to travel through Xinjiang in August 2012. Imam was always very prompt in responding to queries from each of us and helping to coordinate our various flight schedules.
We had a hiccup with the Turpan-Kashgar train tickets halfway through our trip as the guide made a mistake with the train times, and Imam was very prompt to rectify the situation even though it was Eid that day; he had us brought to Urumqi and organised flights at no extra cost to us so that we arrived in Kashgar on time.
The transport provided is very comfortable. Lily was an excellent guide in Dunhuang and Tudajim was a superb guide for the Muztagh Ata trek: we were of varying fitness levels and he managed us all very well; if you are thinking of booking with Xinjiang Travel I highly recommend asking if he is available.
