I'm chairing the "Providing Professional Drupal Services" track for Drupalcon San Francisco in April and am looking for interesting sessions and speakers to help seed the Drupalcon sessions list. We already have some great folks on board. Sessions will be opened up for public submissions soon and the earlier your session gets added, the longer people have to vote on them.
So, if you're interested, ping me with your session idea. If you're looking for ideas, I've put together of potential subject matter for my track here, as well as a Drupalcon Talk Idea Generator to get your juices flowing.
Disclaimer and clarification: I posted this with the goal of connecting with people who are thinking about or have already prepared sessions for the track I'm chairing. I'm not in charge of fielding all Drupalcon session proposals and I won't be the one that decides which sessions ultimately get chosen, but I should be able to help folks with the submission process.
