Best Company for Nursing Seminars

Everyone,
I just graduated with my masters in nursing education. I originally thought I wanted to teach in an academic setting, either BSN or post-baccalaureate. Well, I find the academic world constricting. I've been to some fabulous seminars and think I'd do a great job teaching and holding an audience's attention for 8 hours.

Who are some of the companies putting on the better seminars in nursing education?
What are some of the most interesting formats you've encountered?
Which speakers hold your interest the most?
Thank you in advance,
TDub
