Your have good GPA and a remarkable corporate exposure. Per your Profile and GMAT score I would recommend you to target Kellogg, Harvard, Wharton, UCLA, SDA Bocconi, Duke and Ross Business School etc. As the average GMAT Score for these B Schools fall in between 650-790 range.
You are in perfect stage of your career and around 5 years of work experience is what most B Schools look for.
However you would need to cleverly prepare yourself for questions like why you had a low GMAT score, the reasons you want to switch from IT to management, your rationale behind applying for a specific B school, so on and so forth.
The next step for you is to focus more on your application essays & recommendations for these Business Schools.
Hence it would be highly advisable to seek assistance from professional consultants for guidance on preparing a good letters of recommendations and get your essays/scholarship essays evaluated before sending it out along with your application.
