Advice on becoming a bartender to earn some extra cash?

I'm a college student but I could really use a night job as a bartender to earn some extra cash. Can anyone give me advice on a good school to go to? (I'm in Philly).) Does the school help you find a job? Do you enjoy being a bartender? Is it easy? Any info would really help this clueless girl out! (Most informative gets best answer!) Grazie!
