There are free meditation courses on the internet. They come around regularly and work by sending you an email each day for you to listen to and follow. A friend convinced me to join him doing a 21 day Deepak Chopra course which I find a bit light and new agey, but I notice Spring Forest Chi Gong is also doing one. Both are in mid session now, but will probably relaunch later.
Spring Forest is sponsored by Learning Strategies: http://www.2012springforesthealingfestevent.com

Undoubtedly there are others. These are closer to beginners level and have a bit of a commercial feel to them, but for the price, why not.
If you know when others are going to start, let people know the email address and when.
