I need help with writing/ghostwriting a book

Hi, I am looking to write a book. The book I'm looking to write I want to be around the disability services sector in Australia and basically a 'how to' book. A book I've read recently that I liked the style of was Jack delosa's 'unprofessional'. The story I want written ideally I would like to be a mix between an inspirational story and a 'how to' book. I can provide the majority of the content, my only issue is getting the information out, and communicated in an effective way. Ideally I am looking at about 140 pages. At this point I am unsure about an appropriate budget as this is not something I have previously looked into. Please feel free to message me and further discuss. Thanks, Chris
