Any Yoga Instructors?

[Conservative Hippie]

I'm thinking about taking a certification course through YogaFit. It costs about $350 (yikes!), but I really enjoy yoga, and have an idea for my own studio some day. I'm a little apprehensive, because I've only been practicing yoga for five years, and there are a lot of poses I can't do (crow, anyone? head/hand stands?)

Any instructors? Where did you get certified? How much did it cost? Where do you teach?
