Well, I always appreciate people with ambition, now you got one. :)

1. Spread the words in your communication circle which is your own heart, your family, your friend and your social media connections.

2. Start from your own self, dont ask for dowry.

3. Start Campaigns like I mentioned in my third comment before HGL arrives with his own thought. I will share it again for your easiness http://www.chimeforchange.org/

4. If you have already took dowry give it back to your FIL or wife family, may be they will feel relieve with their debts etc
