Since you have a low GMAT, don't have recent work experience and are not looking for a full-time programme your odds of getting a scholarship are limited. I suggest you improve your GMAT.
Use this method http://www.find-mba.com/board/33571 to find the best schools for finance. With the exception of LBS, the top ten schools for MBAs in UAE finance roles are NOT in the UAE, but in India/Pakistan or the AUB in Lebanon. Looking at people in finance/banking/investment (rather than those in other industries) the pattern is the same.
PS One of the Pakistani colleges has a UAE campus: http://www.preston.ae/
What is your view of executive mba in cass and executive mba in hult (both in dubai) ? which would you suggest to choose for my profile assuming am offered places at both schools.
