Friend Newsfeed

Hi, I am working on a site which currently has a topic post system in place and a friend system, I am looking for someone to build me a page that shows a feed of the topics created by themselves and/or friends sorted newest to oldest, like facebooks news feed. TABLES IN THE DATABASE Users - User info Friends - Friend relationships Topics - Topic Info Tags - Tag info for topics Topic Tags - Stores the relation information between tags and the topics. This site is currently offline, but I can provide files to show how he site is currently functioning Thanks
