This is far too little information with which to evaluate your chances. Get a couple of years of experience and then come back and ask.
Regarding your question, schools look at entrepreneurial experience very favorably. Just be sure that you can answer the "Why an MBA?" and "Why an MBA now?" questions. You don't want to look like you're applying to b-school only because you couldn't succeed as an entrepreneur, and you also don't want to look like you started a business only to try to get into a top b-school.
