Wow, I can remember when I was asking this question! Well, what worked for me is to have at least some sort of portfolio ready to go, and if you're on facebook or mysapce, to have a port available there so they can see you're not just creepy old guy with a camera. Business cards are very handy as well. See if you can have a second profile just for your work and contact people via that profile.
I know that I am one with beauty, And that my comrades are one. Let our souls be mountains, Let our spirtis be stars, Let our hearts be worlds.
