Okay there's three ways to go.
1 - You sell us your book copyright for one lump sum. We then try to sell it to the world and make millions of dollars (yeah, right).
2 - You write a book, we help you edit, design and publish it then we both market the book and split profits. We share the copyrights and both of us try to sell the book anywhere we can.
3 - You write a book, we help you edit, design and publish it then we agree to buy alot of copies of it for a very good discount. You keep the copyrights and are free to sell the rights anywhere you can.
NOTE: Most people seem to like the third option best but understand that unless your book is completed and only needs a distributor, you have a long way to go. The hardest part of book writing, publishing and selling is that no one sees any money until the public buys your book. Chicanos tend to be very suspicious people and they often don't seem to appreciate the collaborative nature of this industry.
