Get some exposure. Though you can skip this step and move right on to trying to sign with an agent, it couldn't hurt to have your face out there and to have some modeling experience so you have something to point to when you approach agencies. Try to appear in local newspaper ads, TV shows, magazines, or even fashion shows. You might get the attention of the right people without even appealing to an agent directly.
NOTE: This does not mean that you should get absolutely any work you can. Remember that you're trying to build and maintain your image, so don't do something that is completely below your dignity, not taken by a real photographer, or which doesn't represent who you are at all.
Do not shoot in anything less than your underwear unless you're getting paid. You may be told that you should shoot nude or an implied nude to get some free photos, but you should avoid these kinds of offers like the plague. Don't shoot nude unless it's for a professional, reputable, and established company that pays you for your work. If you take nudes with sketchy photographers, who knows where they will end up.
