I have more questions that answers. Are you looking for a professional ghostwriter or something more on the lines of software or books that tell you how to write your memoirs?Amazon.com sells several books about how to write your life story, available in paperback or Kindle format. There are many types of software designed to help writers, and I think there is at least one that provides templates and guidance for writing an autobiography (though I can't recall the name of it).
There is lots of other 'how to' information on the Internet, including numerous articles that tell you how to go about writing your life story and even suggest various approaches to take. That's because you would write in a different manner for publication than you would to record your life story as a memory book for family.
All you need do is type "how to write my life story" in a search engine and see what you get.
By the way, I have worked as a ghostwriter for a client's memoirs before, but because it is much more work than writing my own material or even editing for other writers, my ghostwriting skills do not come cheap.
