Hi SuccessfulGMAT,
From what you've written in your initial post, it's not clear whether you actually "need" a tutor or not - so before you invest in that type of service, it would help if you could provide a bit more information on how you've been studying and your goals:
Studies:
1) How long have you studied so far? How many hours do you typically study each week?
2) What specific study materials have you used so far?
3) On what dates did you take EACH of your CATs/mocks and how did you score on EACH (including the Quant and Verbal Scaled Scores for EACH)?
Goals:
4) What is your overall goal score?
5) When are you planning to take the GMAT?
6) When are you planning to apply to Business School and what Schools are you planning to apply to?
GMAT assassins aren't born, they're made,
