3-page web design and make it 100% Responsive like a10.com

Hi I am in need of a 3-page responsive design / I need the files delivered in HTML5/CSS3/JS ready to integrate I recently hired a design firm and they totally messed up my vision for the design, I need it fixed and make it 100% responsive to the users screen size. I attached the old design that doesnt work as well as new screenshots to how new design should look. Here's the site i want to mock after [login to view URL] Requirements: - Make the header fluid and responsive to users browser width (check out [login to view URL] drag the window size around, see how its responsive) - redesign image thumbnails to look like [login to view URL] - make homepage game images responsive to users browser size (copy [login to view URL] code) - on gameplay page make game as big as users screen (see [login to view URL] code -- drag the window size around, see how its responsive and changes game size... --- i need to be able to set the flash object to 100% width by 100% height and the scaling happens on its own - also game should take up 90% of the game div box like [login to view URL] - make the search page SEO friendly Also, we need very fast and efficient code to make the site run fast -- i am guessing if we use code from a10 it will run fast :) Let me know if you have any questions
