Create a Website Purchase, Sale and Exchanges like e-bay

This project will be a site for buying and selling like eBay, except that the focus will be on exchanges. For this, in addition to products offered users must do their "wish list". The platform should be able to do the matching between the products offered with the desired products. making this correspondence and suggest this exchange opportunity for both users. For this to work well the most important is a "tree products" well built. I do not expect the developer to finalize this tree products, for I myself will do after delivery. I hope you have a tree of basic product that works well and is operable and expandable for me to work on it later, the most important is that it is dynamic! Some basic requirements. * Meteor (framework javascript) and Neo4j (nosql for graph) * Page Responsive * UX * Bug Free * Payment method * Well configured in Amazon AWS * Design * Chat Simplified System * Users of reputation system well done * Basics of Gamification for reputation * Social Features (feed-date noticiais with products of interest) * Tree of Dynamic Products (will make the structure of the tree static and products can be embedded in this structure of dynamic way, as if they were tags autocomplete with) * SEO
