Are there local guides for Shishapangma?
Yes but the Chinese have made significant changes recently favoring only Tibetan guides, cooks, porters and staff. You will definitely need some type of assistance. There are many quality choices based out of Kathmandu that can help with logistics. Some are less expensive than traditional Western companies but most charge about the same price. My usual advice is to get recent references from a climber with a similar background and skill level as yourself. Get everything in writing. Finally ask about food, group gear and language skills.
