Custom message board

Im after a very basic message board for a website that I'm having put together in PHP. Ive found something that I like the look of at: http://www. [login to view URL] There are some slight changes that I'd like to make to it, styling & emoticons (which i can do) and a search facility,... but basically the format should remain the same.? I'll also need it to be usable by my site members so I'll need it to integrate smoothly with my original sites Login feature and styling - same fonts etc, but I can help with this. I can also put you in contact with my original developer and you can work together to integrate the board seemlessly into the sites original design. Timescale and pricing are important to this project. Many thanks Dalton
