Are you looking to get in for this fall?
I know you said that you don't have time to do the re-take, but between spending more time on the written application vs. a GMAT re-take, in your case it will make sense to make that tradeoff and focus on the GMAT.
With your score, you may be able to get into schools like DePaul, but the top part-time programs like Kellogg, Chicago are likely out of reach. Same with the CA schools -- places like Irvine, Claremont, LMU, Pepperdine, Santa Clara, San Jose State, etc. may be possible, but schools like USC, UCLA and Berkeley are out of reach.
If you can bump that score up to the mid-600s (and ideally close to 700), the top programs will be more within reach.
p.s. didn't Ben Roethlisberger go to Miami of Ohio?
