I know tha you do not want to go the Ebay route, due to the fact that you may not make a full profit, however it has become apparently obvious that no one on this board is showing interest in your beautiful gown.
Have you tried the other wedding sites- UltimateWedding.com, TheKNot.com,WeddingChannel.com? There are new brides registering everyday who have yet to purchase a gown, you may get lucky.
