Overall you have a solidly good, although somewhat middle of the road candidacy. Being female will help though differentiate from the rest of your relatively large pool. With your background and GMAT Booth, Haas and Duke are preeeeetty far stretches for you, so you may want to remove them from your strategy, as that will be really a LOT of applications to do (although BRAVO to you if you can make it!)
For other schools, you can also look into Fordham, Madison, and Ohio State, which all have highly ranked marketing programs.
For Singapore programs, of course it depends on the university! I suggest starting off by looking at the employment and salary statistics that the school publishes (and that you can often find reposted on the FinancialTimes rankings) That will be a good indication of the job opportunities through each school you apply to.
