Auction & Community Marketplace

Need help completing website design and coding for an auction and community website. Auction interface is already created in PHP. Need to graphically customize it. Want all sections of the website, not just the auctions, to require a user to log in. Want to create user profile section. Copy, basic design and graphics already created. Other projects on our wishlist include: blogging capabilities for website users, ecards, rating auctions and posting images for viewing by all users in a non-auction area of the website.
