This video is about a year old so some of the pricing has changed, but the ideas are the same. Also, I didn't realize the correct mic wasn't being picked up until after it was all recorded, but I didn't feel like doing it again.
That said, I'll be doing an updated version with more current information soon (which will be part of the Classroom Levels), at which time I'll remove this video. But for now, this is a good place to start.
Enjoy!
