bartering with a twist - open to bidding

Not quite sure how this works. Before we begin. you know, I need a very strange Cascading style sheet. Do you build the main frame. I sample it. If I like / love it you sell me the Key / License. The front page will be about the customer and there go green, bartering story's If you view my version, you might get were I am going with this software. [login to view URL] were they can post Photos, Video of there Ideas, and such. Of course I need a buy swap sell or Goods, Real Estate, Services, and if Auctions and or bids be added to this section as well. I would like my Games, Community events / Forum, and my bartebates, to be on another page. Of course the normal stuff like Contact us, / Our story/ terms / Privacy / And most important login in form, membership levels, for a set time membership, with set trail days. and the news letter. Can we build in sections! just incase, I cant afford the whole bill at once. Helen
