I would also like to recommend Award Travel Consulting and they only charge $100 per booking:
http://www.awardtravelconsulting.com/ I am new to the game and ATC helped book two F class award tickets using US Airways DM. They take consulting to a new level because we experienced a bump on one of our segment back home and could not get in touch with US Airways but luckily I was able to get access to a computer before boarding and emailed ATC with the predicament. They gave US Airways a call and had the problem resolved when we arrived for our next connection flight.
