CMS - Implementing some Javascript into Wordpress and Joomla

Hi, i am looking for a Javascript implementation into CMS like Wordpress and Joomla. It is a mainly a Parallax Site, Video and Text with different speed. It does NOT have to be a perfect plugin like solution (which would be great) but it should be manageble by non programmer. If you worked with parallax JS like tweenmax or / and Skrollr before, please provide samples. I will provide a link to a page which comes near to what i need so you can check 4 yourself. PLEASE, ask for the LINK which shows you what i need...so i can Filter out who is reading this Text and who only Bids without reading it. Any Bid over 50$ will be ignored. Thank you...
