@ Narz: I think this is a really cool idea given your 3 acre set up. I have known people to have, and have myself had some very bizarre pets, including snakes, rats, owls, big grey parrots, pigs, chicken, goats etc etc. Now I live in England I would never have any pets. They need to be given appropriate space to roam around, not be kept cooped up in a house.
FYI - I don't know of anyone in India who has a pet monkey. In the general public, monkeys are feared in India for carrying disease, they are avoided much like stray dogs are. You do get those guys with performing monkeys but they ain't pets man and you also find monkeys hanging out around Hanuman (Monkey God) Temples, but again they are not pets.
