I've taken the image from the email and rotated the hue towards the blues. The numerical values correspond to the Hue slider bar in Photoshop. On my monitor, the -20 value looks the most like your business card.
I want you to take some time and look at this on lots of different computers, so you can make an informed choice about which version looks best to you. Then you can ask the web designer to simply rotate the color on the art and repopulate the pages.
The content area looks too saturated, to my eye. Did you want that much color in there? That's a separate issue, but easily solvable. They ought to be able to show you a short set of swatches.
I love the sun, mountain, water and rocks together. Looks nice! Too bad the navigation has to be buttons instead of CSS rollovers (it would be so cool as pale purple text that bumped larger and white), but it's not really that important.
Well, I hope this helps you get what you want.
