Thank you for the overview of your profile. While you have a decent GMAT, based on the information you provided it would be necessary to come up with a pretty powerful story to explain your situation in a way that would appeal to admissions committees at the schools you mentioned. That doesn't mean it isn't possible, it just means we would need to dive into your profile a bit more before determining. On the surface, the odds are stacked against you because of the lack of experience, but I have seen applicants with similar profiles have success because there were other things under the surface that made the difference.
What college did you go to?
What was your GPA?
Extra-curriculars / leadership in college and today?
What do you want to do after your MBA?
You could benefit from taking some time to work and delaying your applications, but let me know the answers to those questions above and I'll give a better and more specific recommendation.
