Is this a coded contest? Currently there is no category for 'coded' designs, it has been eliminated. You will need to find a coder to code the final design that you pick as a winner. You may find that the winning designer is a good coder also and you can negotiate the terms with them privately after the design contest, or you will need to find a coder via the "Looking to Hire" section at the main Sitepoint Forums.
