Seeking a memoir co-writer

I've long wanted to write a memoir of my parents and me and my siblings lives, but feel daunted about the the project. Thus I seek someone to help me pull it all together. In a nutshell, my paternal grandparents were both from Ireland and met on the boat when grandpa (one of 21 kids) was emigrating here and grandma was coming to stay for a few weeks with an aunt in Chicago. They ultimately married and went on to have 10 children, my dad being the youngest of them. My parents met in their early years married and had 5 children (actually 7 of which one was stillborn and one was my twin who was born first tho not fuly developed and then I came into the world via breach right after). I'm the middle child and only daughter of the five. One of my brothers was diagnosed with schizophrenia in his late teens which of course had a big impact on the family, especially my parents quality of life. Both of my parents have passed - mom in 2019 (age 84) and dad (age 90) this year in March of 2022. Mom suffered from onset of degnerative stroke disease and dad from dementia whic my siblings and I witnessed and dealt with firsthand. I am an avid reader of memoirs and would love to put my thoughts down on paper and recount my life's story. I need help to get things started.
