Currently are no off-the-shelf skins available for purchase. There are 2 themes available with nopCommerce, nopClassic and DarkOrange.
Creating your own custom theme is very easy to do if you have good css skills. Just copy an existing theme folder in App_Themes and give it a name of your choice e.g. "MyTheme". Then in Administration > Configuration > SEO/Display tab, set your "MyTheme" as the store theme.
You can then make any changes you like to the css files within your custom theme folder.
If you would like a theme developed for you then this is a service we (RetroViz) can offer, or you can post to the job boards (Product > Job Boards) on this site. However, I would recommend you have a go yourself.
Hope this helps,

Your better to go somewhere like 99designs.com and pay for a top quality design that is NOT nopCommerce specific then ask a nopCommerce developer to implement the design.
However this is going to cost a lot more than premade design - If you are serious about your store and want a top quality finish then I suggest going down this path.
