How to Catch Tuna

I'm after a book on how to catch more tuna. I'm not expecting something huge - about 40 pages - 50 max. You will be required to do some research to add to the book along with appropriate illustrations, photos or images. I have approx 30 pages of information that I can provide to you that will need to be edited and rewritten. All the information in the 30 pages should be included along with any other information you can add to the book.
