Sorry, have to agree with others, out of all three I prefer the original! I asked my partner too, she's better a colour/white balance etc. and she preferred it too! Of the two new designs I preferred A.
I am with the others in liking the original design, but I think design A is much stronger especially in terms of its calls to action in the content area.
However, I don't think you could lift them and fit them with the outer of the current site. I think they need the frame of the green design to balance them.
I would be inclined to go with design A but lose the far outer vertical green bars altogether as I think that would make the page look lighter and easier on the eye.
So it's design A for me with the slight modification of removing the far outer vertical green bars.
I had a look round your site last week (nosey moo that I am ) and really liked it (LOVED this page especially http://www.alocalprinter.com/uk/people/ ) so was somewhat surprised to see this post today. I agree with the others that your current design is much more visually appealing, but could perhaps do with some tweaking, just to keep it fresh.
Not too keen on the new designs - I can see they're good designs in themselves, but green really doesn't do it for me I'm afraid, especially the darker shades. Would be an instant turn-off... though I do love that funky little tree illustration, so keep that somewhere
I still prefer the original design of the site. It looks more clean and professional compared to the new design. But if you still want to redesign it, I think Draft B looks better compared to draft A.
I am going to go against everyone here and say that I like B best with a few little tweaks.
1. Instead of having the green for the side bar and the footer background, have it white as this is where all your text/content will be and so you will want to be easily readable.
2. leave the green background as I think this will look great with the green tones in the main header.
Plus I do have to say Ray, I am not a great fan of your current styled drop down list with the rounded corners.
