I just checked the design and I do think that it needs improvement. For instance, the navigation at the left is quite old-fashioned and also not good for usability. It should ideally be pushed on the top.

The edges and border radius of certain elements is just not complementing well enough with the rest of the page.

Now coming to your problem, I think you can take the help of http://sortfolio.com/ which has listing of really good web designers.

On a sidenote, I am a designer myself. Just in case if you need any help you can reach me at [email protected]
