WANTED: White David`s Bridal ML9521 Size 2 Or 4

Do you have a white David`s Bridal style ML9521? or 7ML9521 (the petite)? I am looking to buy one since I can`t afford the $600 price. I need a size 2 or size 4. Please let me know what alterations have been done (bust, waist, bustle, lenght), and how much you want for it. I can spend $150 plus shipping. Must be white. Need it before April 2010. I am not interested in Replicas or dresses from outside of the USA. Thanks!
