Wanted Melissa Sweet Or Monique Lhullier Gown

I am getting married in October 2006, I fell in love with the Melissa Sweet Style Hallie gown, and I also love Monique Lhullier Style Monet gown. My budget does not allow me to spend anywhere near the price of these gowns, but I am hoping to find a knock off for a great price. I live in Riverside, CA and would like to find someone in the Southern California area. If anyone can help I would really appreciate it. I am a size 4. Thanks so much for the help in advance.
