You should check out Nepal Himal Treks for local guides for Everest http://www.visitnepal.com/nepalvision/nepalhimaltreks/about_us.html. The team is led by Pertemba Sherpa, one of the most experienced and well known Sherpas in Nepal. We've used them on numerous occasions and they run an exceptional outfit.
Also, check out Chile as a potential training ground for your expedition if you are short on time and cash. Ojos de Salado, the highest volcano in the world at almost 7,000m is a great place to start, and easier on the budget than crowded Aconcagua.
