Profile Eval-Indian female/Marketing/640/4yr WE

I am a 26 year old female from India and applying to US business schools in 2012. I have a GMAT of 640 (Q:45 / V:34 / AWA:4) and a TOEFL score of 96. I have worked for 4 years as a marketing executive in India in the hospitality industry. I have worked for two different hotel groups 1) 1 yr at a large single hotel located in the commercial center in the capital city of India 2) ~3 yrs at a large multi-national and multi-brand hotel chain, with responsibility for nationwide (India) marketing. I had hit a ceiling at my company and without an MBA they were not willing to promote me further or give me additional responsibilities. So I quit and for last 2 months, I have been working as a full-time volunteer for an NGO for differently-abled and underprivileged children. By the time I join a business school (hopefully), I would have worked at this NGO for almost 1 year. I am passionate about dance and was part of a professional dance group for 5 years (alongside my college and job). Both at college and as part of this dance group, I have performed at multiple shows with audiences of 1,000+ people and won many awards. I have an undergraduate degree in English (Hons.) where I studied English, History and Philosophy. I was very active in my college’s dance and theatre society. Indian colleges do not have a GPA system. I would consider myself a firm mid-tier performer academically.
I am very keen on continuing a career in marketing. Can you kindly advise which schools will best suit my profile? I am keen on Duke, Haas and Cornell.
Thank you very much in advance.
