I highly recommend Amerasia, especially Paul. Last year, I decided very late in the game (basically <2 months before R2 deadlines) to apply to business school, and was introduced to Amerasia by a friend who also had a good experience with them. 

Even though he had a number of clients and I had a very tight timeline, Paul still took me on and helped out every step of the way, from selecting schools, to editing essays, and prepping for interviews. Prior to working with Paul, I spoke to a number of other consultants, and found that the majority of them used scare tactics. They insisted that that I needed an “expert” to help put together my application, that there was no way I was going to make it alone.
