You also need a reel in many styles. You can go to the Prelinger Archives and download all kinds of interesting video clips; just delete the audio and put in your own score. Choose things that you don't like in addition to things that are fun; they challenge your creativity. You can also do the same clip several ways - drama, comedy, suspense, etc.; the music changes the entire perception of the visuals. That will get you started until you get a few shorts under your belt.
A MySpace/FaceBook/etc. page with examples of your work will also assist in finding gigs.
