I also don't think you neeeeeeeed a photography course to achieve what you want to achieve. Put that money into your next lens.
You have the internet. Teach yourself. The information is out there, you just need to want it. Learn the basics, get on Google+ and add a bunch of photographers you like to your Circles and follow them. Add Fickr users as contacts for you to follow if you like their images. Check their EXIF data on their photos to see how their photos were taken... that can be an ok learning resource.
I have actually gone to the trouble to create some playlists on YouTube that feature the best learning videos that I have come across. I have broken them down by subject. Spend an evening, with your camera in your lap, going through them. Pause when something confusing comes up, play along with your camera... you'll learn a lot trust me. You'll learn more if you go out afterwards and shoot, shoot and shoot some more.
