Please help us to volunteer in Nepal

Joanna and I would like to volunteer in Nepal providing free anesthesia services to children with deformities for reconstructive surgery. We will also be working directly with 140 children of Nepal Orphans' Home and providing medical care to villagers in remote areas. Our trip is planned for April 20, 2013.
Joanna is in anesthesia school with 10 months to go and seeks to go on this trip with the blessing of her school. I just recently graduated anesthesia school. I enter active duty in the Air Force in May and Joanna enters active duty in the Air Force following her graduation. Financially we are not in a position to do this trip now, but if we don't go now, the window of opportunity will be closed for a couple of years.
Please help us to go provide much needed services to orphans, children in desperate need of surgery, and villagers without any access to medical care. The cost of our trip is approximately $6500 for both of us for 2 weeks. Any additional money raised will be given directly to Nepal Orphans Home, a U.S. based 501c-3 tax deductible charity started by my father 8 years ago.
