Beat The GMAT a GMAT & MBA community

Hi

Aim is to join in the fall of 2013. My under-grad finished in June 2009.
Acads
GMAT - 750. (V - 42, Q - 50) AWA - 6/6
TOEFL - 120.
CGPA - 8.7/10 (places me at the top 15-20% of the entire branch, top 10% in the class)

Work-ex
Cisco Systems - 1 year (2009-2010). Awarded a star. First up for a promotion. Topped yearly statistics. Awarded a great rating etc etc.

Abhitech Energycon - 2 years this June. (2010-2012) This is a rather small firm, and I made the switch because of my MBA aspirations. You know the drill, small firm larger exposure. And thats exactly what I have managed. I am working at a level answering to just the Board of Directors. I have been the youngest of every post held by me. Individually contributed significantly to the firm's revenue. Travelled 15 countries in Europe and both the Americas. Multi-tasked immensely. A lot of responsibility, leadership etc. By the time I join a school, I would be 3yrs old here, so a total of 4yrs work-ex. I understand its not above avg, but I have really toiled hard to compensate for that in regards to the QUALITY of work-ex.

Extra-curiculars
Lead the most successful dance group in college.
Won IQ competitions. Wrote for the year books. Have done quite some volunteering since graduating. Been editor + director of comunity service at Rotaract. Long distance runner. Astronomy buff. Taken classes. Taught under-privileged since my own late teens. Built robots etc.

There maybe some small bits I am missing but this should be 90-95% of the package.
Going with my score, I was really wishing for programs like Harvard Wharton MIT Stanford Columbia Booth Berkeley and the like. What do you think are my chances? Any suggestions apart from these schools? Am I over-dreaming? Where can I further strengthen my application?

I would be much obliged if I could have your thoughts here.
Thanks so much
