I just organized my own Annapurna trek and used a great guide. I organized it thru a good friend of mine that is Nepalise and runs a travel company in Thamel. He speaks good English and really ensures you get what you ask for. He's a friend because I stayed with his family while volunteering at a small village near Annapurna. Contact Giri and see if he can help!

Drop in at the KEEP office in Kathmandu (just google "KEEP Kathmandu"). this is an independent organisation looking after porter wellfare, and can give you good advice regarding hiring of proters. Situated on the edge of Thamel towards the east (Royal Palace) side and just north of Tridevi Marg. Note they've relocated so older guidebooks (pre-2010) may show their previous location more central in Thamel. about 8 years ago
