It will be good to create a site name ' Bitcoin Talk Market Place ' Where any one can come to show their product and buy and sell all things in Bitcoin. Satoshi Nakamoto wants to sell his Bitcoin Magic Mouse to raise $200,000 Dollars to donate to a charity. He will publish an Auction Notice soon.
Without you knowing there are already many sites that runs such kind of business. One of them which is I am very familiar with is coins.ph this site is an escrow site that exchanges local currency to bitcoin and vice versa. But on the back-office they have this section for merchants wherein merchants and shops will post their items and accessories in exchange for bitcoin.
