A Php Script Similar to Behance or Google Plus

Hello developers. I wanted to know, what is the PHP script(s) that is similar or a clone of Google Plus, Behance or Twitter. I want a script I can buy and customise. If possible I would like something that allows video uploading or embedding and as well as digital marketplace for the user to sell his digital products like music, videos, eBooks or images. Anyone with an answer inbox [e-mail removed]

I’m sure there’re not too many items on the CodeCanyon for PHP script parts but you can also use the search feature to eliminate some other products - considering those, I don’t think it’d take lots of time to find the item if it exists at the marketplace
