I need the website of a large international organization converted to a responsive pattern. You can take a look at for example [url removed, login to view] to see the type and complexity level of the website (this is not the actual website). You'd be expected to analyze the existing site, and then create CSS for about 8-10 different landing page types, including the homepage, based on the mockups that WILL BE PROVIDED by me. All mockups will come in three sizes (i.e. two/three breakpoints on the page, depending on how you count it). You'll also use whatever other tools necessary for adapting the website to mobile use (e.g. JQuery Mobile for making menus touch-friendly etc.). You'll remain on hand for any assistance required when integrating your work into the website.
This is a serious project and bids will be sealed. We want a top quality contractor - it's best to bid only if you can show a solid portfolio of similar websites that you've executed. Any other questions - let me know.
