Convert Website to Marketplace Platform (Updated)

ClassDOX is currently a platform that allows the user to create/upload notes, share notes, and manage his notes through our content management system. We would like to add a layer on top of the current platform which will make it a buy/sell platform. In order to do that we will have to create a few forms, limited note preview using scribd api, implement PaypalX API, and some changes on our home page. Home Page: we would like to add a small table that list the most recent notes uploaded for sale. This can be seen in [login to view URL] Within this table randomly loads 10 notes on every reload of the page. Note Preview: When a user clicks on the "preview" button to view the note before he/she buys, they can only get a limited preview. A space for the note price will be created where user can see the note $price. Once the note is bought it will be put in the user class folder. [login to view URL] Profile Changes: Profile setting will be added mainly to manage the Paypal account address -- so we can forward commission to them. [login to view URL] Selling a note: A field will be added where the user will put the price that they would like to sell the note for [login to view URL] We will be also removing few extra features. But we will be keeping the code -- NOT deleting it. For reference to types of features we will be integrating you can see here: [login to view URL] TO VIEW OUR EXISTING WEBSITE GO TO: [login to view URL] AND TO VIEW OUR NEWEST FEATURES GO TO: [login to view URL] Here is more specific look of the phase requirement profile changes: [login to view URL] [login to view URL] Table Content of My classes [login to view URL]
