To be honest, you'll be a major wild card. Hard to say where you'll end up.
B-schools may publicly say they value entrepreneurs, but they still ideally like those who have had some corporate experience (i.e. those who have had prior experience working for someone else in a corporate environment before starting their own biz).
The reason is twofold:
(1) Your ability to work well with peers: being your own boss is great, but if you have had little to no professional experience working with people as equals (or those who are more senior than you) where you can't always get your way, adcoms will be concerned about whether you will be that loose cannon or not when it comes to working with your fellow MBA students on various group projects
(2) Recruiters: you can say that you want to continue on with your biz, but adcoms will assume (no matter what you say) that you will also be recruiting as well. As such, recruiters will be also concerned about your ability to be a team player -- you've always worked for yourself, so what will be the adjustment like to working for someone else? Can you work for someone else, work for a boss?
You may feel that in your case, these two issues are minor because you know you could do it, but the hard part is convincing someone who doesn't know you that these won't be concerns.
And that's why it'll be very hard to say what your chances are. All you can do is apply, and hope for the best.
