All the schools should be within reach except for HBS and Columbia (if you apply, treat them as lottery tickets). At this point, just focus on doing the best you can on the GMAT and go from there.
Also, not sure about hedge funds given your work experience. You will likely have to work in sales/trading or investment banking post-MBA beforehand, because you'll be up against a lot of highly qualified folks with strong finance backgrounds (i.e. those who have already worked in Wall Street type jobs).
