You are approaching this problem from the wrong angle. You are asking "how do I set up cryonic arrangements in India", which as far as I know nobody has ever done and is probably going to be very complicated and risky and expensive to figure out and carry out by yourself. Instead, you should ask "how do I bring my relative from a 3rd world country to America", which is a MUCH more studied problem, with already established methods and infrastructure that are known to reliably work.
Convincing them to get frozen is hard enough as it is...I'm up against belief-in-reincarnation for at least 40% of them.
Also, I myself doubt that completely uprooting the life you do certainly have, in exchange for a shot at immortality which has a high likelihood of not actually working, is worth it. There are established business in place, and losing proximity to extended family together is a huge deterrent, even for most of the younger generation.
At best, it would be worth it for the very oldest relatives who are nearing the end of their lives...but...
