Branding Concept Needed

Hi, I'm Creative Director for a new agency and we're just in the middle of building a new website that we're really happy with, however we are struggling with a colour scheme or theme that we can use throughout the site on slides and on images for our different departments. We're looking for an illustrator or very good graphic designer to take a look at our new site, our existing branding (that were happy with) and come up with maybe a couple of nice looking slides for our homepage. We will then recreate the imagery throughout the rest of the site using the direction from the work you've done. Hopefully this makes sense. Its only a small job but we have plenty to throw your way if this works out well. Thanks!
