Any writers want to help me write a eBook?

Right not it is 20,000 of the 70,000 words goal; I mainly need help with humor, realism and filler to complete it.
So far i am having my friend make a legal documented contract to show that in return the helpers get credit in the novel.
The book is pro weed and deals with issues of life like a bad job, having autism, and more.
My contact that is on here more is kik: wulf1477
