How to pitch to attorneys?

[Jeet Sangha]

Hi all, 

I'm making a list of attorneys I want to approach for referrals who specialize in wills and estates, divorce, bankruptcy and among others. Main idea is lead generation if they have clients who need to sell a house the attorneys can refer them to me and in return i can pay $1000 if we close on the house. 

What pointers you guys can give me on how to approach them?
