Wedding In October.... Must Be Under $2000- Bay Area

We`re seriously trying to plan our wedding for October/November 2008. We live in the Bay Area. We have 2 lovely children so expenses must be minimal. The guest list is about 40 or 50 people. I get so stressed out just thinking about the planning. I already have the dress. I have the stationary to print out my own invites, and that`s about it. If anyone has suggestions please let me know! xoxo.
