Writer Needed for Autobiographical Project

Our father is looking to contract a person to assist him in writing a book about his professional career as a structural civil engineer here in Canada and in Ethiopia. To a lesser extent, the book will also describe his life. The book would be around 150 pages or 50,000 words (flexible). He has Parkinson's Disease so he suffers from mobility issues that prevent him from typing. We're looking for someone who is patient and can work with him a few hours a week to help draft this book. We're open to working with new writers looking to build a portfolio and more experienced writers as well. The timeline for the completion of the project is flexible given his condition.
