I want to get a web design done at 99designs.com. From my understanding, after this coding and installation of word press(I want WP) needs to be done. Is there anything else? Is there a need to hire a graphics designer too? Also I want to know if I can hire a person who can spruce up the page with visual elements and highlighting is to attract, engage and motivate the customer towards making them use our services. I dont know what such professionals are called. What I'm meaning to say is that I want to hire a person similar to a visual merchandiser but for the web.

Thanks
