How many of you remember $1 a month donation box by Mahabir Pun? He is now opening his own restaurant to generate profit and use for his village internet project. because he is out of money by donors. He should have done this a long time ago by donors money and earn profit for his noble cause.

One suggestion from my side is:
I don't know if she has children big enough to do some kind of small business like Donut making and selling in their free time after their study. There is a big profit in that.
The money generated from Sajha, she can invest in buying floor, kerosin oil, stove. The profit she made from that she can pay loan little by little. This is just my advice. A lot of street vendors are surviving like that in Kathmandu selling momos, pani puri. But she needs some extra help for sure. She will not be able to do this alone. She is also an old woman.
