Clone the functionalities of Aboutus.org.
It is a website listing service with info about the site taken from its meta tags along with several useful statistics like ranking, PR, etc. Wiki script is fine and you can use as many scripts as you think will be beneficial but of course keep the site secure.
It also has to have a user rating function, as a hot or not for websites.
Javascript, php and mysql is a must.
Lowest bid will be chosen and only if a bride idea of how to approach the structure of the new site.
You do not have to clone it 100% but have to make a site that serves the exact same functionality and features. Good luck.
