Can anyone recommend a dealer in Coral Springs, FL?

A friend up here has an Aunt down there who would like to sell her gold coins and silver certificates.
You now know as much as I do. She sees the ads in the paper and doesn't know who to trust. She asked her niece to find a reputable local dealer. Any assistance is appreciated.

The Philadelphia Mint: making coins since 1792. We make money by making money. Now in our 225th year thanks to no competition.

Edited to add, I believe Stack's has a buyer down there just north of Ft. Lauderdale - close to Coral Springs, actually. Obviously they are reputable but for bullion there should be someone in the area that works on smaller margins.
