Looking for iPhone App developer who can set up a auth/communication to a server via protocol buffers.(Must be experienced in Objective-c, Python, Google Protocol Buffers and so on)

Looking for a experienced iOS developer for prototype project. I'm looking for help on setting up a client-server auth/communication via protocol buffers. Must be experienced in obj c, google protocol buffers and reading python (reading c++ might be useful). The server is written in Python and there are already desktop clients written in Python and a c++ prototype. I'm creating a mobile client for iPhone and need help with the communication to the server. This is only prototype project and urgent job. Deadline: 1 week East European are preferred. Candidates will be provided detailed spec.
