Promote Movie App in WhatsApp

I’m looking for someone based in India who already manages or owns active, genuine WhatsApp groups—especially local city or community circles—and can introduce my new Movie App to those members. For the trial run I want the link and poster shared in just three to five of your busiest groups...
