i'm giving up - there's no way ticketsmaster's allowing me to sell my tickets.

here's the story: i bought a couple of tickets, which i won't be able to use. i wanted to sell them here, face value, but then relised i'm supposed to pick them up on the eve of the concet from ticketmaster boxoffice.
i now live in isreal, and they are only willing to send them over up to 4 days before the concert, or (after i'd pay extra 18 pounds) - up to 7 days. that won't allow me to sell them to anyone. they also won't send them to any address that's not mine.
they also suggested i pass my credit card no etc. to the buyer, and he/she will present them in the eve of the concert, and there should be no problem. but i need this buyer to trust me in order to do this.
i'm absolutely stuck here. can anyone sort this out?
thank you
