Hi,
I'm bayuadji, a python/django developer.
I've saw your project description, so you will want to developer an API that can be used by 3rd party.
here's some thing that I would do:
1. I think it's best if we're using REST based on HTTP, its easier for the client, because it's only HTTP.
2. since we're using REST, so we can still use DJANGO for our endpoint, and using either django-tastype or django-rest-framework.
3. authentication usually bit tricky, but I think we can use simple approach by using key in header authentication and IP firewall.
of course there's other approach as well, and I open for discussion (but please don't use SOAP :), its painfull working with SOAP in python )
my rate is 15$, and I'm available at the moment for 12 hours a week. I suggest that we do a small milestones as a test (2-3 hours), see if I match your expectation or not.
that's it from me, looking forward for further discussions
regards
