CSS3, HTML5, jQuery, Javascript expert

We're looking for someone who is amazing at CSS3, HTML5, jQuery, Javascript and can work full time for the next 7-14 days. We have a SAAS website building app that we need a little optimization help on the end pages. This is what we need help with. 1st) we have 80 templates that have already been sliced, that we need someone to go through and optimize as much as possible, find errors, make sure they are mobile responsive, etc... (we'll give detail on what things we need to make sure are working) 2nd) we have a lot of other templates that are not sliced yet that we need sliced, optimized and installed into our SAAS app. 3rd) we need templates tested within our editor app to verify editing of text, rich text, images, and videos behave correctly. If any issues are found they should be fixed, changed deployed, and tested again. #3 is the biggest right now and where you will start. You need to be able to push the updates with GIT instead of FTP. Ideally we'd like you to be able to run ruby on your computer so you can test locally, but it's not required. We are looking to get started ASAP. Thanks
