I have written a series of books what should I do now?

I have written a series of 5 books I am 16 years old and tight for money and don't know what to so with the books. They are all aimed at children and are diaries written by sportsmen and women. The five books are called: my diary: a racing driver, my diary: a cricketer, my diary: a ballerina, my diary: a Footballer, my diary: a rugby player. I also have some other titles but haven't written the book yet. I can upload some of a book onto here if you want to read some.
