You should look over the stats in all the traditional places--usnews.com, businessweek.com, etc.--and see where you fit in. Your GMAT score is a bit on the low side for the top schools, and your lack of work experience won't help you, I think.
But a lot of the schools have been making a big deal about getting more "non-traditional" students in their programs, so if you've got something special going for you, you might have a chance.
