Development of Q&A site similar to allexperts.com - repost

We are looking for a Python developer to help us design and implement a system which has the same functionality as the site: www.allexperts.com. The only added feature is to create an elegant way to change the language of the user interface (i.e. to Spanish, German, French, etc.). We can provide a more detailed spec if you are interested. Our preferred framework is Django, since we have most of our existing functionality on it, but we are open to suggestions. Please in your response mention any relevant Python or Django development experience, any online samples or github open source contributions are a big plus. We are a small team of Python developers working in a growing internet site, and our hands are full, even if this is a medium size project, there will be more work down the road. :) We are looking to develop a prototype within a month, and then having a finished product a couple of months after it.
