Django Social Network onGoogle App Engine

I need a social networking website similar to facebook done in Django and Google App Engine. I need someone who is familar with Django to complete this. The feautres I need are member's profile, multi lever FOAF. (Phase 2 links, forum, groups, events, site blog and members' blog.) Every page will come with flag it (adult, abusive, subject to moderator's decision) comments, rating and voting. Log in will be with Google ID but we have a Catcha. (Phase 3 OpenID and Open Social) We must use Google's Big Table for database. Caching. Secure, Fast and HA. Thanks
