Website background graphic and logo

Hi there, I run a website and I have built a brand new site in Wordpress using the Jigoshop plugin. I am looking for a fabulous website background and also a new logo, utilising the cartoon mice currently featured in my present logo alongside new cartoons of other small furry pets in a similar style. I know the sort of thing I want and I need a designer who is good at the "cartoon-style" of drawing - colourful and funky without being too "kiddie-like". My customers love small furry pets and are a bit bonkers so the site must reflect this and be a funky welcoming place to shop.
