Maggie Sottero Brielle Wedding Dress

Hi! I`m in desperate need of the Maggie Sottero Brielle wedding dress. My wedding is September 6th, 2009. From what the bridal shops are telling me, I won`t have enough time to order it without paying a lot extra for rushed shipping. I wear a size 5/6 in street clothes. I`m looking for this dress in a white or diamond white color. I`m hoping to find the dress for less than the bridal shop`s price. Does anyone have a Brielle dress that they are willing to sell? Thank you!
