Quite simple, really. You send me 1 BTC to 1HkvrXuoNRfxpfiNd79K9B1Qrp3pxSheXi (the escrow address). Now your 1 BTC is safely held and you will have offers coming in left and right. In fact, it wouldn't surprise me if you sell it within 1 minute of the address being funded. You get the $314 in your account, and I release escrow to the buyer. Easy.

We'll keep an eye on the address. Just waiting on you to fund it:
