Beta reader for fairy tale book

i'm looking for someone to give me a thorough critique of my modern fairytale book (approx 50'000 words). It is set in England and revolves around a much loved fairytale. The characters are 19 and 17 years old.I am looking for character, plot, structure analysis and would welcome bids from people who have already received high ratings on this site. Please don't post extortionate bids as I'm not a millionaire.
