If I were in your shoes I would build a list of potential mentors as I read blogs, books, articles etc about the topics I am interested in. Then I would rank them roughly in order of preference and then contact them one at a time and explain that I am looking for a mentor and give a brief summary of why I chose them and a brief background on myself. I suspect you wouldn't have to go very far down the list before someone agrees to be your mentor. If after a while, I wasn't getting what I wanted out of the mentor that agreed, I would explain this to them, thank them for their time and continue down the list.
