Here's a few thoughts for you.

1) I go to Elance / Odesk and know that I will virtually always find someone to do what I need, no matter what it is.

Programming and design work are more than likely two of the largest areas of these types of sites.

You have 9 people offering programming services and 16 people offering design services. That is simply not enough choice. Considering the big guys have hundreds (if not thousands) of people in these categories. You're not even close to being "10% as good" as your competitors.

Considering the people offering services are essentially your "product", you don't have many at all.

2) When people are searching for people to hire, you should make the job images, along with the job title clickable. To find out more information I currently have to click a little blue link under the image and text description. It's not intuitive design.

Along with the that, once a category is chosen, IE programming you need to be able to narrow the search even more.

It's not a problem now as you don't have many freelancers but eventually, crawling through 20 pages to find 1 Wordpress will not be acceptable.
