A good place to start would be The Permaculture Research Institute of Australia which Geoff Lawton heads up. They should be able to provide you with information about the best permaculture projects as well as the best teachers closest to where you are going. If you are fortunate enough to connect with a mature permaculture system in India, they may be able to provide you with plants or seedlings for your own home project along with valuable information for that climate.

There are probably permaculture links for India as well. I'll see what I can find over this next week.
