I need somebody to advertise my books

I have three books that I published myself but I need somebody to get my books out there for people will pay and read them. The first book is called "Unisex." Its a book with Poems in it. The next book is called "Nine Short Stories." This book has varies short stories in it. The last book is called "Wild & Wilder". This book is about varies animals. I need somebody that knows what they are doing for cheap. Before I pick somebody, I need a detail plan on the following: How are they going to advertise the books? An estimate of how many copies they will be able to sell? Happy Bidding!
