Build an Online Store

Hello, I have a great brick and mortar business selling supplements, food, and body care products. We pride ourselves in great customer service, but have been unable to get a really good looking, functional online store up and running because I don't have anybody who knows the back end of magento. Right now I have a magento site, with integrated shipping module installed, and some minor things configured, with about 100 products uploaded. I need somebody with some experience in static blocks, banners, etc to make sure our site looks good. Our goal is to build one of the best Health and Wellness sites available, so if you can convince me you are the right person, I would like to have a an ongoing working relationship, to continually make the site better, and slowly expand into more countries. The first project would be to fix find this missing css file for me.

If you can fix this problem for me there will be more work:) Website is [login to view URL]
