Combining Twitter & Facebook feeds

I have code in PHP to pull Facebook and Twitter feeds to a webpage. What I need is to mesh them together and order by post date. • The meshed feed needs to have a limiter (for example latest 4 from Facebook and latest 4 from Twitter) • The output code needs to be styled depending on the feed source (so Facebook posts will look different to Twitter) • The output must recognise if there is a blank post (for whatever reason) and not just print a date - this happens on some FB pages I have attached the PHP & SDKs for both feeds. CSS Styling is something I can do, so please do not attempt this. Please provide a working example and I will pay for your code.
