Hi Akashyap13.
It's true. A good GMAT tutor can easily cost $200/hour or more.
So, have you considered using a self-study course? A good self-study GMAT course can show you everything you need to learn for the GMAT, provide practice, and even provide a study plan.
Also, have you prepared at all so far, and have you taken an official practice test yet? If not, determining your current level by taking an official practice test will help you decide how to prepare.
On another note, with 14+ years of experience, maybe an EMBA program is really what you should go for. If so, you could take the EA rather than the GMAT.
