There are many places where you can grab very liberally-licensed graphics. If those don't do whatever unspecified thing you need them to do, they can probably still serve as a base since it's easier to modify than to start from scratch, especially if you find SVG/Inkscape/whatever source too. A bajillion web designs can be found too with liberal licensing. The combinations of liberally-licensed graphics and liberally-licensed web designs opens up yet another easily-accessible vista of design combinations.

Someday when I get around to it, that's what I plan to do with my site. (Once upon a time, I decided to do the design from scratch myself. What have I learned since then? I'm absolutely, utterly terrible. Oh well, lesson learned.)

Look around, search for things with Creative Commons commercial licenses on them. You'll probably be able to come up with what you need.
