Convert a Template to a Website

Hello there, I basically need a fixer! I am a C developer student and I accept a paid gig for a luggage startup. Now I'm in trouble. The delivery date is the 22th of november. I build a single page website with a background video in html/css/jquery by taking pieces of code everywhere and it needs some improvement: - The video background won't loop on firefox: so a javascript workaroud or jquery. - Some css cleaning 'cause a lot of classes are colliding because of the code theft. - w3 validation - A stylish email popup with the plugin jquery magnific popup on clicking the email logo - add a div with the company name (I tell you where). the email popup must come out from this div. - a media query for the mobile version. I'll provide the source code. Thank you.
