However, if an agent agrees to take on your work, when she places it, she will earn a 10-15% cut of whatever money you make from the sale. So if a publisher offers you $10,000 for your book, your agent will get $1,500 of that money. You will get the rest.
You can get an agent the same way you get a publisher: by finding a book on how to get them (such as the one by Jeff Herman) and sending them query letters.
