The absolute, sure fire way to get rid of shyness is to face it. Perform as much as you can. The shaking is not from being shy it's from being nervous. To get rid of nervousness, perform. Just do it. I took acting classes for 3 years, so my shyness disappeared within that time, but alot of magicians are shy, no matter their experience level. Alot of professional magicians are shy/nervous when they perform, but they have mastered how not to show it. That's what you've gotta do.
