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.
OP I think you need to explore this forum well because there's a section dedicated to what you're talking about with several sub categories where you can do all this.
