Hey there and thanks for dropping a line, dude.
So let's cut straight to it, shall we?
Overall, from what you wrote here, if you can hit that 700+ your profile has potential. I can't say much much more than that, because I don't yet have a clear vision of your work experience, nor of the extra stuff. But things so look promising, and your list seems reasonable. From your list Columbia and Duke will for sure be the challenges for you, and just HOW challenging will depend on that final GMAT score you pull.
And best of luck with that!
