Small job to edit an ecommerce site

I created a website using 123reg because I had hoped it would be simple and for the most part, I'm happy with it but the eCommerce part seems to be uneditable. I can't get it to look good. So I need it redoing so that it displays nicely and works as it's awful currently. At the moment there are only a couple of products but there will never be more than 6-8 so I don't need lots of categories. The images and information is already there, it just needs playing with so that is displays well on all mediums (phones/tablets/pc/mac)

Thanks
