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 django, jquery, and also psd2html and photoshop. Currently I'm in developing another job here with this technologies, I almost completed and it we be finished tomorrow, so I'm ready to start ASAP.
I can send you small demo project in django (using twitter bootstrap), it is not published.
Actually I didn't work with web service, but trust me it will not a bid deal.
Also I want to finish it and move to the next stage you are talking about.
Yours
