As @sniper told you, your local college, tech school or university is a good place to start.
Also there you will probably find foreign students who are willing to tutor for some extra needed cash or more often than not, for trade in tutoring one hour of their language for one hour of English. It's a win - win for them because they don't have to spend money for often much needed help in English. If you don't have the time to spend with them and have the money to pay, then that also helps those looking to tutor. College bulletin boards, school newspapers show ads sometimes for these things. Also you could approach the Foreign Language Department of the school because they often know people/students willing or looking and could tell you about classes and language lab services available. It's a good way to start if you're serious about leaning a foreign language.
