Now, his idea is that lot of NGOs in various villages have to make this investment of 1200$ (which is a LOT of money for people living in villages), install the machine, make the napkins and then sell them.
What the OP and I suggest is that he should create/install machines in his own factory, optimize the process even further and then using economies of scale create cheap napkins which every women can afford. Having a central location to drive the prices lower is much easier than installing machines in a country as big as India. And I think he should be able to easily get Investment because his invention is featured at the national level. [And if he can't get Investment, I will start a kickstarter project and send him the money.]
