Are you looking for an internship or your first job? The larger cities always have loads of catering companies. And most of these are always looking for help. I would try and find a mid-sized company to work with. Too large, and you would end up, pretty much as just a grunt for quite awhile. Too small, and you wouldn't get a lot of different experiences, as they tend to only do smaller type parties. A mid-sized company would be perfect. Big enough that you might get to work some large 750 people + parties, small weddings, coporate events and picnics. Plus, if you show an interest, these companies are not so large that the chef may have the time to take you 'under his wing' and teach you more about all the other stuff that goes with catering.
