To the OP go by here http://elmfork.com/
and introduce yourself and let then know you are new to shotgun shooting and they can get you started out correctly. They also have guns to rent both O/U's and semi's and offer lessons.
"Did anyone here actually begin shooting with a coach? I'm not talking a friend that knew how to shoot, etc. I went to an Orvis class after I had been shooting 30 years,"
From the way the OP was worded he's completely new to shotgunning and there's a big difference between "shooting for 30 years" and just getting started. To shorten the learning curve and getting shown proper form/stance/gun mount and help in learning to read targets. I would recommend getting some lessons.
