Writing coach needed for new writer and new book

I am just at the beginning of my book writing journey and need help with refining the book idea and coaching throughout the book writing process. Ideally, I would like someone with knowledge of publishing/self-publishing as well.

My book will be on life lessons and use this blog post I wrote as inspiration:

Some ghostwriting is an option. I also need help deciding what writing software to use.
