You can check sites like this one echinacities or thebeijinger. Go under the city you are interested in and they should have a listing of jobs in certain categories. Then you just apply and hope that somebody responds and once they do respond back immediately. That's one way!

That is a really vague question.  You will need to provide more details so we can give you better guidance.  Otherwise, generic BS like Mattie dishes out will be the best you get.
