Python + Django/Pylons dev needed for Music Web App (streaming, social community, group buy)

I'm looking for Python development for a **funded** first iteration of a streaming music community web application featuring one-click purchasing as seen with [BuySimple][1]. You and your team will need to be able to, in essence, rebuild [SoundCloud][2] and integrate a one click purchase model as seen with [SoundRain][3], incorporating group buy functionality as well as one-click purchases across blogs and publications. User Interface designs will be provided in whatever format necessary, what we're really looking for here is a functional backend to get this off the ground, with full purchase capabilities. Please contact us for more information as to the details of core functionality and proprietary characteristics if you're up for the job. Python development is of course required unless you can convince us otherwise. Experience with building into merchant gateways and streaming media is preferred as this will be crucial to our first build. Equity in addition to project costs is possible as we're looking to work with developers in the long term, not just on a single aspect of what will prove to be a very large project. What we need now is just a first working product, customers and traction, if you're interested and agile we'd love to tell you more about what we have in the works. Thanks!
