Thanks for sharing your profile. I don't have quite enough information to give you a truly involved recommendation. It does seem however that you have a clear interest in entrepreneurship and assuming that you will continue to invest in and grow your business in school I would identify schools with a strong reputation and coursework in entrepreneurship. Also, I am assuming your business is technology based this may be another area you filter your school list against. Schools like Berkeley and Carnegie Mellon may be programs you should look into. Overall identify the qualities you are most interested in from your schools and create your list based on this then gauge whether you will be a fit by the numbers (GMAT/GPA) then start making a more informed decision.
