Ghost writing for a novel ( Please read the description carefully before applying)

Need a ghost writer who is a perfect mix of captivating writing and understanding of concepts of time travel, physics, mathematics etc.The project is about both fiction and sci-Fi writing. If the ghost writer is not so well versed with science part, I appreciate if he can rope in some science expert who can team up to oversee the science part and come together to blend the fiction+ science aspect logically. I appreciate someone who is naturally interested in Science& fiction in tandem. My budget is 1000USD .Good Luck.
