Check out meetup.com for meetups nearby. If you're lucky, you may find some bitcoin/cryptocurrency groups.

You could consign the item through someone else's eBay account if you would like to sell it on eBay, which would be a pretty good option. You could also post more of an ad on eBay, requesting offers through messages (likely against the TOS).

Alternatively, sell it on the marketplace here on bitcointalk.org. You won't get some crazy price like you might on eBay, but you can get some pretty fast and easy bitcoin this way.
