Has anyone hired book writing services before?

When I had a surgery of my leg there was a nurse who use to take care of me at night. She used to read and write. One day I randomly asked why don’t you write a book as she was a nurse and she has different shift timings and a family to take care of due to which she couldn’t take out time. I suggested her about affordable book writing services, as they experience and can write a for you as you want. Who can guide?
