Hey Pragmatist,
Sounds like we're in pretty similar boats. I recommended Manhattan Review to another fellow in the forum. See the following thread: http://www.www.urch.com/forums/gmat/102858-recent-college-grad-looking-gmat-assistance.html
I spoke to their reps on the phone and they were helpful. Not sure of your exact needs or timeframe, but here's is a link to one of their promotions.
