life history 85 years old

I'm looking for someone to create a detailed life history of an 85-year-old individual. The specific purpose of the project is to document this person's family history, and I need the life history to be written in the first person. I'm not sure which events should be emphasized in this life history, so I require somebody with experience and knowledge of producing compelling life histories that provide a balanced coverage across the lifespan. As the success of this project is of great importance to me, I'm looking for a reliable and dedicated freelancer who will work closely to ensure its success.
