Design and PHP changes to an existing script

I need the following changes to be done to an existing vine sharing script: - Completely change the look in terms of the design - Add a section called More Vines (which features about 20 vines) - Add a section called popular vines (similar to [login to view URL]) - Do some minor changes around the script PM to find out more about the script. And show relevant work done. We will first start with the design process. The current script is mobile friendly; I want the new design to be like that as well. Experience with vine API would be a plus.
