I need graphic design for my ecommerce website

The website is work in progress, check it out here: infinity-projects.co.uk. All the graphics within are temporary and we need everything redesigned. We'll need a logo, icons for the circular thumbnails, designs for the rectangular promotional banners, and perhaps something to go in the slider near the bottom. The requirement is that it must all remain thematic, colour coordinated, and with matching styles etc. We're also open to ideas on graphics for promotional content from you guys, would be good to get a more creative person's perspective.
