Estate Planning USA.com

The realtor(or realtist according to his business card) we are working with in buying a house offered us a plan to improve our credit so that we can get the best rates possible. My husband is all for it but I am a little hesitant since we dishing out $750 for a start up fee and $250 monthly for his assistant to call, write personal credit letters, one on one coaching, among other things to get us both at a 650. I am concerned since this is alot of money and I looked on the BBB website and cannot find this credit management group or even her real estate agency in its reports. How do I tell this is a legit operation and not just someone trying to scam a young couple out of a few thousand dollars.
