Turtle Island Voucher for Sale

I have a turtle island $6000 travel voucher to be applied to your turtle island vacation. At the time my finance and I were going to get married there. I paid for our deposit plus my family and friends deposits. Unfortunately, she got cold feet and left me holding the bag $6000 bag plus the other wedding deposits, I would have taken the trip If it wasnt for the fact I cant disassociate turtle island with her leaving me. Therefore, I willing to sell my voucher to anyone for $5000 or Best Offer

Did you have any luck selling this? I'm in a similar situation and would love to sell this! Thanks for any advice. :)
