Article website

I want to host a website which should have good articles and contents for readers. you can keep this website [login to view URL] as benchmark for the work to be done and off course i want my website to be simpler and easy to use for readers. I need all the features of above mentioned website and if someone promises for some added features on top of that then project will be awarded to that party only. Project should be implemented in any of the good CMS system like **wordpress** or **joomla**. Parties who are experienced in developing solutions in these CMSs should reply...!
