get a general app, fill it out and make a bunch of copies. get cleaned up and look sharp, go into local businesses and ask if they have any job openings or open positions.
also, even if you haven't had job experience, try and get a job doing something that you do as a hobby. for instance, i love cooking, food, and going out to eat. during my interview i told the chef that i had never worked in a restaurant, but i love food and cooking. i got hired that night.
this is what got me a job as a prep chef in one of the two top restaurants in town, and ive never worked in a kitchen before.
