You have a very strong candidacy. Your work experience looks excellent and you do have a strong GMAT score. If you do not believe your score will increase by 30+ points, you should not be concerned about taking the test again.
I recommend you read this case study of a candidate who worked for one of the Big 4 accounting firms: http://www.stacyblackman.com/2011/09/08 ... eer-goals/
Is there a specific set of programs you are interested in? Do you have a preference in location?
Hope to hear from you.
