Catering Deal In Atlanta, GA Area

Hi,
A woman I work with used to be a professional meeting/party planner/ caterer before returning to grad school. Her office parties and food are delicious. She`s offered to plan and cater my wedding (312 people) for $5,000. This sounds like a good deal, is it? The only thing she won`t provide is the cake and liquor. We had a tasting (4 courses) this weekend and it was delicious. I was just wondering if it`s a good deal for those of you who have done a little more research than myself.
