Business plan help

Hi I’m a student at Iowa State University. I’m an animal science major and I’m taking a class called Equine Systems Management And our final project is to make a business plan for an different equine careers and I went with behavior management for horses and the owner and I already wrote up the plan it’s 20 pages I just need someone willing to go over it and let me know if everything works out and if the numbers make sense. My professor hasn’t been much help with this
