Trying to find qualified help

I am desperately trying to find a doctor who fully and completely understands sleep disorders to help me figure out my problem. Do you have a referral source that recommends only highly qualified practitioners in my area? I have had the normal sleep studies, both at home and on site, with so-called sleep centers and their sleep doctors, but they have not provided any helpful recommendations - just that it is not apnea. They said I moved my legs 375 times in the 4.5 hours I slept, but since it did not cause me to wake up, they claim it is not a problem. I have tried all the CBT-I recommendations and am very nutritionally aware. I have done a lot of my own, lay person research, and have tried many, many things thought to be helpful. I need someone with in depth experience to help figure this out. Thank you for any assistance.
