Qoute request

Hello I wanted to know programming code as I am not sure on this project I am thinking off.
I want a similar site programming to Site point/ Deviant Art.
It should have a log in area, personal cp, automatically a user could submit there work and people would post and comment on it. It will be an auctions site so that people could bid and son. The projects would feature on the top page in certain categories. The Cp must have all of the user new updates, display pictures and so on.

All help appreciated
