Children's Book Illustration -- 2

I have written a short children's book. Thid is my 2nd children's book. Looking for someone to work with me for free on it to do the illustrations. I was thinking very simple black and white drawings (I can provide sanple illustrations from my first book). This new book is about grandmothers looking for their grandchildren because they miss them. I am making it for my family but will also shop it around publishers. You would get a cut and cover credit if I sell it to a publisher.
