we recently lived in india, i wouldn;t bother buying things to sell in india to be honest, everything loses vale there very quickly.
all i can remember about customs is it took 15 hours to get out stuff that we had sent over and they tried to bribe us out of alot of money, so my best advice for that if you know someone who can help bargain them down. also the paper work is extensive and long.
if i can help you out with anything else just let me know :-)
