Wedding canceled :( Finding someone to sublet?

Hey everyone,

Due to some extintenuating and unfortunate circumstances my fiance and I have to cancel our wedding. We are really just trying to postpone it until next year. Our venue was beautiful and on the water and we loved it. We just wanted to push the date and were hoping they would use the deposit as a fee for changing it and allow us to schedule it later. With some confusion and tricky wording in their e-mails with my father ( who was paying for the venue), what my father thought was just a deposit to hold the date, was taken as a first payment. Basically we are stuck in this situation and we have to pay the full price for the venue on our original wedding date, October 9th. As you can imagine it is very hard to pay for a venue that we arent using and on top of it have to pay for a venue for our actual wedding this coming year. My mother was told that in these situations some people are able to sublet it to another couple for a cheaper price. We don't have much time so I have little hope that we could find someone in need for this date but if we were to sublet it, does anyone know where to post it? Is there anyway to get out of paying the full price? There was a death in the family. We can't have the wedding this soon while we are grieving and after the the costs of the funeral and such we just can't afford it all right now. Any advice would be much appreciated.
