Love your concept of homestays in rural India. I can provide you with the requisite information. Having done my Masters from the International University of Monaco, I am a personal fan of monetizing farm stays, promoting ethnic and local culture. I can provide you with the needed list bifurcated state wise.
Being engaged in the work of travel and tourism websites, I already have the experience of listing relevant profiles, people, addresses. So, I fully understand your context and will deliver what is sought.
