AjithBtc, if your friend is looking exclusively for local sellers, then it would be best to look for them through LocalBitcoins. Of course, given the size of India, it is possible that he will not find anyone living near him, but it is still worth a try. Keep in mind that this type of trade carries with it certain risks, because if the amounts involved are large, the possibility of robbery should always be taken into account.
All things considered, I would recommend that you do a little research on some things on your local board - this would certainly be a good start ->
