I need rss feeds from Youtube, twitter, FB and more

I need a rss feed that pulls content from Twitter, youtube, Fb and more depending on keyword/s. Also have option to not pull feed if has certain keyword. very simple , just need rss function to pull from as many social platforms as possible. I prefer to able to add to my php site. There may already be plugin or code for this, so if you can recommend the exact plugin or option i need i can give 20$ to you or if you code custom than can negotiate price for that if reasonable.
