I'm not particularly qualified to evaluate the credentials of someone coming in at your age/experience bracket, but I thought I might make a suggestion.
Most of the top 10 will have a "technology" subset which suits your background. While you might go into general management consulting just fine, you might find more success in the application/interview process in one of these subsets since you're more uniquely qualified for them. Depending on the firm, this sub-set could deal with things from CIO-level IT strategy for non-tech companies to IT cost improvement to general business strategy for technology companies. You can also edge into the "general" group from the other positions a lot of the time. I have an MIS background as well, and I had much more success applying to these sub-sets than I did to the companies in general.
Examples of these groups include McKinsey's Business Technology Office (BTO) and Booz's IT Strategy practice.
Hope you found this helpful!
