Agents are rarely interested in short stories - many will tell you that they don't sell. Linking short stories to make a novel is a difficult one - there have been some examples, like The Martian Chronicles. But generally they are two separate and respected disciplines. Entering short story competitions - getting yourself out there - is the best way to attract a publisher/agent.
