Book writer / editor

I need help in writing my memoir story in a form of book /ebook to be published.
I have hired a professional caricaturist here Who's (gratefully) drawing the scenes of an unfortunate tragedy I passed through about ten years ago. I explain to him what I went through and he translates it into scenes and scenarios by drawings.(examples attached)
I want to do the same in writing In order to combine the words and the drawings in one complete book to be published and documented for.
I'm not a good writer, therefore I need your help in turning what i went through into a live memoir with all the feelings surrounding it.
Hope I explained what is needed well.
Grateful to you all.

I was asked about the words count. I did not have that in mind. I needed some help from you. I assume it's arround 30k more or less.
