The best self promotion you can do is to talk at user groups. Find a Python/Django/whatever user group in the nearby and propose to present a speech. You don't need anything particularly sophisticated, any technology/framework you have used is just fine.

Often user groups are struggling to find people willing to do presentations, and they'll glad to give you the opportunity to speak. And they are the best place to network and find new jobs or contracts.
