Request for Profile Evaluation...Thanks

Hi,
Im a 25 yr old Indian male in an IT MNC. wishing to apply for the fall 2012 courses.

GMAT score :750

Here is my Professional profile-
4 yrs of work exp (will be arnd 5 yrs by fall 2012). For last 1 yr, working as a Lead Engineer and leading a team of 4 people (2 freshers and 2 with exp more than me) for Quality Engineering activities.
Consistently achieved highest ratings in appraisals and a number of recognition and awards for the same.

High point of the professional achievement is the team's successful completion of testing automation for one client, which will save them a lot of effort and time in future.

Within the organization ,have been associated with various councils setup for employee engagement activities, Leading a team of 6 people for one such council and an active member of community service council, which involves volunteering for providing education for underprivileged children.

Academics not so impressive. Managed a 70% in graduation (Bachelor of Engg), no idea how much is that in GPA.
Although during college I had been involved in organizing TechFestivals and together with few mates laid foundation for a Personality Development forum which organized debates and extempore.

I'm looking to apply for colleges in top 20 but such as Duke,Darden, McCombs Texas and Cornell but I also need a good scholarship. something which covers 60-70% of the total cost for the program. Is it possible in top 20ish univs?

With the "Indian IT male" tag and academics being a rather weak point , what other universities can I consider while applying?

Thanks in advance for the suggestions.
