I think your profile has potential and you have basic credentials that will make you a viable candidate at many top schools. However, I'm concerned by your career goal and your lack of work experience. In order to gain acceptance to an MBA program you will need to be able to better articulate why you need a degree. One part of this is understanding how a business degree will help you achieve your future goals (and what those goals are). In your case, I might start with your long term goal (to be an entrepreneur) and work backwards. You don't need to have your post-graduation dream job set in stone, but, you need to discuss industries and roles that you might seek. It is perfectly fair to state that you want to explore a few different business roles in order to have an understanding of all the various elements that go into running a successful business. Perhaps a rotational position at a big company would suit you. Or, if human resources is most interesting then you should discuss this (but with more conviction!).

In order to present a case for yourself (saying you want the job with the most money is NOT the answer!) you should consider what type of entrepreneur you plan to be - what industry? what type of company? do you plan to make something or to offer services? Are you interested in technology or finance? do you plan to buy companies that exist or start something from the ground up? If you are unable to answer these questions now, I would suggest that you gain more professional experiences first so that you can make the most of your MBA.

I am not familiar with many of the schools you have listed, but, for US schools, remember that your recommendations will be a big part of your application package and these will need to come from people you have worked with in a professional manner. Internships of one or two months will not really suffice. I would suggest that you start building long-term professional relationships now in order to be ready for next year's application cycle.

Good luck!
