Hi sarss2306,
First off, a 730 is an outstanding Score, so you can comfortably apply to any Business Schools that interest you. As such, a retest is probably not necessary. What were your Quant and Verbal Scaled Scores - and what specific types of Programs are you interested in? You're ultimately asking Admissions questions, so you would likely find it beneficial to speak with an Admissions Expert about your overall profile and plans. Those Experts should be able to answer your Admissions questions and help define the specific areas of your profile that could use some improvement.
There's a Forum full of those Experts here:
