Quikr type website

Hello, I am looking for a website which would have something similar to Quikr.com. I would want to create a Market Guide sort of website. So would like classifieds in one of the tab. I understand that there are many a classifieds scripts available. But I want some more features and facilities into the same. I would also like to have a forum added up, so as to have debates, etc. Polls, Wordpress type something integrated so that the blogging of information can take place. Kindly do bid only if you are serious about it. I need to have it soon. Also if you have something ready, would like to have a demo of the same. Thanks and Regards Edward Katchira
