I can do it, I'm new to this site but I have more that 10 years of web development, so I am focused on a work done, happy client and a nice review instead of money.
I have big experience with python/django, javascript/jquery, twitter bootstrap, w3c standards, git, also psd2html and photoshop. In my profile you can see employer feedbacks of my previous work with all those skills. For your site I can use MySQL as database, and jquery and twitter bootstrap for ui. I can send a demo I have done with those technologies for another client.
I also can make automated tests for most functionalities (TDD), a thing that consume me time but advanced clients likes.
Yours,
Julio Cesar
