Planning to develop about 3 themes for somebody. What the fastest and most efficient way to design a word press theme and how much time would be required to develop a quality and good looking theme for word press. I have given as estimate of 2 weeks to the client to develop 3 themes for his websites. Is it a realistic timeline or should i ask for more time to develop his wordpress theme. All of these themes need to be developed from scratch and must support the latest version of wordpress. Any suggestions from you guys.
