Hi,
I can start working in your project immediately. I have a server for POC purpose. I offer you to install all frameworks for your evaluation. I suggest you to install Plone for a professional website. I have enough experience using plone. It's so easy to customize it, with templates and lots of moudules to extend functionality and have more features.
It's not common to use plone or any CMS based in python, but do you know anything about Ruby or Go? But's there is and idea of a CMS behind all them.
Experience in using PostgreSQL, apache and Python.
Please drop me a line if you are interested in my services.
