Overall you have the following things working for you in your profile:
-higher-than-average GMAT score at all programs mentioned (congrats!!)
-solid work experience including progression and people and project management experience
-the public sector financial consulting for government is not so common so may be of interest to the admissions committee
-extracurricular involvement (better than none!)
Potential areas of weakness:
-your undergrad GPA
-not much in terms of community or volunteer experience
-may need to demonstrate more through your application, what makes you unique, what you'll bring to the program
-your application essays, recommendations, interviews
So based on the above, much of the decision will come down to those 'unknowns.' Be sure not to underestimate the importance of investing time on those essays-- those are the one place in the application where you create something from scratch to represent who you are! You'll need to convey what makes you unique, what you'll bring to the class, why you need the MBA, how it helps your future goals, why you want to change careers, and why you are interested in EACH PARTICULAR SCHOOL.
In terms of your school list, Stanford is the most difficult to get into (also has a smaller class size, compounding that fact); followed by Kellogg & Booth; then probably Haas and then the rest. So do some in-depth research into the programs to see which ones you feel you fit with the best and potentially choose schools from different levels of competitiveness, keeping in mind that each application is quite time-consuming.
