Hi californialove,
One of the 'tricky' aspects of applying to a highly-competitive Program is that those Programs accept a relatively small percentage of applicants (often just 5%-25% of those who apply). As such, you have to make sure that you have a strong OVERALL application AND that you 'market yourself' correctly to each individual Program that you apply to. You might be a great applicant, but if you make a 'mistake' on your application, then you might not get in. While Admissions Experts can't guarantee you a positive result, their expertise can make a huge difference, and greatly increase your chances of getting into your first-choice Business School. By definition, most of the Admissions services that are offered are rather expensive, but there are 'ranges' that might be more acceptable than others.
1) What Schools are you planning to apply to?
2) When are you planning to apply?
3) What type of budget are you working with?
