This is just another scam to separate you from your hard-earned money. The agent charges more than the standard commissions charged by agents. Again, if an agent shows any of the warning signs above, you are most likely dealing with a con artist or incompetent. Seek out a reputable agent instead.

Short stories don't earn enough to make it worth an agent's while. You have not completed a book. . You haven't SOLD a book. . Okay, this one's kind of tricky. But your fiction is going to have to be very promising for a good agent to take you on before you've sold a book.
