Entrepreneur/Non-Profit Background - Hinders admission?

My family has been involved in construction my home country for over 3 decades - we also ran a construction company for a few years and sold it. I was a co-founder and worked there while in college.

A few years ago, I've started a charity (along with my father and friends) focussed on providing housing to the poor. I've also started a software company that delivers architecture based services.
Primary funding for the charity comes from my pocket and a few patrons - and we have helped provide housing to over 50 families. The software company is just starting to find traction too but it's been slow going so far on both fronts.

And I believe going to a good business school would help me learn better ways to get to my goal - provide housing to a set number of families ,while developing my company - I hope the company becomes sustainable and help me put food on the table. (money is one of the primary reasons I'm still here - student loan, etc)

Now, the two things I'm worried about are:

1) Employability/Internship Question - I hear business schools value employable students, students who can get good internships to begin with. Given my goal, does it make me less desirable to top schools?
(FWIW, I work at a boutique trading shop and I'm highly valued here - Personally, I think I will be highly employable in the financial industry. Based on what I learn at business school, I might want to work a few more years here, for capital purposes etc. And I am going for schools that I consider are the 6 best in the US)

2) While I am passionate about my charity and love my job here, I am planning to make my charity work the lynchpin of my applications - because that is what I'd like to do long-term. Will that be frowned upon, given I've been working in the US full-time? (I run the charity from the US and I go back for 3 weeks every year).

Thanks and appreciate the insights.
