Usatravelpro.com.... how to sell vouchers

This ist quite a GQ but I need some advice.

Friend of mine purchased accomodation vouchers and is looking to sell as he has changed his travel plans. The vouchers are for accomodation 4 days Orlando , 3 days Cocoa beach , 5 days Cancun. The vouchers are transferable and can be used anytime for the next year as long as you give them 2 moths advance warning.

How can you sell something like this?

Can you set a maximum rather than a minimum price on EBAY (may not sell for more than you brought it for)

Anybody ever brought something like this.

General pointers please folks.
thank ee kindly.

Would “buy it now” on ebay qualify for max price? Some people have the same buy it now price as the opening price. Hope this makes sense.
