Have you tried my tutorial on Speed Building?
In those lessons I talk about many ways to build speed, either from really slow to medium, or from fast to hyperspeed!
This does take a long time though, so just be patient and try to push yourself with the metronome. The muscles in your hands take a long time to connect with your brain and adjust to higher speeds, which is why most people can't play like Yngwie. :D But I believe anyone can reach a pretty good speed with enough practice.
