Autobiography for My Mum and Dad

Would like to get an autobiography done of my Mum only ( Dad is not included in the scope) . I would like to keep a succinct record of their story. Looking for a crisp, short yet key event encompassing autobiography. Project scope : up to 70 pages of A4 write up at font 10 roman times. To use a ghost writing technique : write as my mum is the one who wrote it. You will call my mum on VOIP to engage on her story - cost of the multiple VOIP calls are part of the project cost. Story to be broken up into chapters based on the countries where she was staying : India - Childhood, Kenya - Marriage and bringing up a young family, South Africa - Kids growing up and then post retirement reflections and message to her kids, grand kids and great grand kids. Pics to be included into the 70 pages : But will not count as part of the 70 pages. Select pics that are post appropriate for each story or section to be added (she will take the photo and send it to you). I would like particular attentions to names, Surnames , place names etc to be more focused on the details so that the reader in time that reads it can trace back the people and places. Focus on the write up is on the key life events and the feelings during those events. I count on you to prod deeply to get more life turning events and feelings out of her to make the write up more fruit-ful. I envision this will take around 45 days to complete. With a series of phone call stretching over a period of time. Its better to break the conversations to 1-1.5 hour multiple slots so that the full story can be extracted.
