I recommend Restaurant / Bar work.
Did it all thru' high school and Uni. Its not exactly glamourous but I never went hungry, ALWAYS had money and always made the rent. Mind you, people aren't big tippers here, which is where most of the $$ came from, but its steady work and helps tide you over until you can sort out something you really want to do. Or you might get hooked on it and be the next Gordon Ramsay!!
Good luck!
