I'd like to receive the name, address, phone number and web site URL
(if available) of all the direct marketing agencies and consultants
who are based in India, including the direct marketing arms of
advertising agencies.

I am looking primarily for companies who advise their clients on
direct mail (sent by post). I am looking for agencies and consultants
who both broker mailing lists as well as advise clients on their
direct mail campaigns (i.e. which lists to use, what sort of creative
to use, etc.)
