D.P.
My son was very similar, I thought I was going to pull my hair out everyday. I got on all the websites I could talked to everyone I knew but couldn't find what would work for him. So what I ended up doing was rocking with him in my lap and singing to him (and lord knows I'm singer) but that seemed to calm him down and after about a week and by accident I made up a song for him and we sing it most nights not (by the way my son is 3). I would say it took about 3-4 weeks but now I can lay him down by himself and sing "His" song and leave..if I listen at the down most of the time I can hear him singing to himself and after a while he falls asleep to himself singing. Don't know if this helps but its what worked for us.
