Track Down Stolen Content, Remove Media, Locate Source

I recently discovered several of my personal photos have been posted on a few different websites without my permission, showing my face with personally identifying information attached. I am needing help in locating these images and possibly others online, having them permanently removed as muchas possible and finding the original source who is publishing them (I have an idea who is responsible.) I'm willing to pay per verified takedown, for milestone achievements or per source identified or a combo of the 3, but am open to suggestions. Experience navigating 4chan required.
