US News has just started rating part-time programs. NYU shows up as 5th with a 675 GMAT and 50%+ acceptance rate. AN extrat 40-50 points on your GMAT would be helpful.

You would have considerably more experience than most of their applicants. You should be exploring executive MBA programs as well. The difference is usually that people in executive programs are sponsored by their companies and plan on returning to their field. They are looking for basic understanding in other functions, but are not as into exploring a range of areas as are more junior applicants. If, however, you are looking to move out of IT, then you want to stay with a broader curriculum aimed at the field you are targeting.

Good luck,
