Is there anywhere you can trade tennis tickets for other tennis tickets?

C: Is there anywhere you can trade tennis tickets for other tennis tickets?
I posted another question earlier…I bought a mini-break package for the Legg Mason Tennis Classic that includes– Mon aug 3, and Wed aug 5. I planned on selling these sessions, but no one has bought them on ebay. Is there any site that you can trade the sessions you already have for other sessions at the Legg Mason Tennis Classic this week? Please HELP, as there is only really one more day I can trade/sell these tickets!
