you won't need an agent, you just need a talent bank kinda thing. An agent is for someone who wants to be the "star" in the movie, not the background action....I guess look thru your phone book or what-not and ring em up. Be warned though - ones that ask you for heaps of money and continue to ask you for heaps of money -> e.g $100 for joining, then a further $200 for photos, then an extra $50 for walking in their door....you get the idea...steer clear of those rip off ppl. e.g "Talent Scouts" in Sydney....
