Need Social Media Site

I need a social media site and apps. Features i need are stories, newsfeed, groups, pages, friends, messenger, video calling, live streaming webrtc rtmp. My budget is only $6,000 so i cant afford to have a social media site built from scratch so does any developers have any ideas and want to take on the job. Maybe a social media script that is out there already and can be customized or maybe a social media site that one of you developers have already made and can customize for me.
