Hi,
As per your requirement, I can create the script to retrieve "list of Interrest of People who liked a Post" and "connect to Facebook Marketing API".
I have developed similar script before. So, trust me, I won't let you down.
I have specialization in Facebook graph API. I have develop more than 150+ Facebook applications. To clarify, you can check my profile.
Please reply to get quality work.
Thanks,
Prabir
