RE: Need some ideas.
Go buy one of those cheap($20) tripods, take the swivel head off of it, and you should be able to drill a hole in the rail on your stand and just attach the tripod head to it.... This would allow you to pivot and adjust the camera both horizontally and vertically. If your right handed put it on the right side and vice versa, so you can move it with your release hand. Also if it's on the right side, you should be able to still see the lcd screen regardless of where it's pointed.
Just a theory, I may not have any idea what I'm talking about though. But it's worth a shot, I think.
