There is a massive leap in quality from the first post to post #11.
That one is much cleaner, crisper and clearer. That is really nice work.
To get people to relax in front of the camera, I always go in front of the camera with them, stand next to them and show them the poses I want them to do. I explain to them, for example, that I want them to stand facing slightly off camera, with their arms folded, or in their pockets, or on their hips. If you want a lady to "pop" her hips, do it yourself - do the girly pose with them. You'll likely get a laugh out of them and they will more relaxed straight away.
Make a joke about the whole process "You look great... Or at least you will do after a couple of hours of Photoshop!" (DON'T say this to the girls!), or something along those lines to break up the awkward silence or stiffness.
If they look a bit stiff (and corporate people quite often are in front of cameras), stop shooting, tell them it looks great, but tell them it's normal to feel weird in front of the camera and get them to shake it out. Shake it out with them.
Don't be afraid that you'll look silly, if you do this stuff with them, it validates what you are asking them to do and makes you look as if you know what you're doing!
Being silly and doing silly poses with my clients is how this happens:

Ok, they're not useable as headshots, but they both chose these images as extras and have them in their acting portfolios as "character" shots. The moment they burst out laughing at me doing silly poses, they immediately loosened up, their shoulders relaxed and their smiles became natural.
I use all these techniques with my headshot clients and it works 9 times out of 10. There will always be the odd Mr Rigid Rigidson of Rigidville, but for the most part, doing the stuff you are asking them to do works - because they don't feel as much pressure to "perform"on their own.
My 2 shots were actresses (who are often surprisingly nervous in front of stills cameras, too), but corporate clients have a personality and the ability to laugh at someone being silly, too. You just need the confidence to do it
