photographer calling anyone that can help

Hi I would like to get as many nudists togther to take photos of.  I am looking to get a book published based on the real naturist.  These shots would not be posed and would just be of people going about there normal life.  As I want this to real age(as long as over 18), race, looks are of no importance singles and couples welcome.  As I want to get the book published and ensure complince with the law I well only take pictures of over 18s as these pics well be nude.  Anyone wanting to take part, or aware of any great locations, ideas then please get in touch.
