About Building and Writing Websites
As for content development (website writing), again, we're talking about time. Here the big issue is "raw material." What is the client providing for basic information. For instance, are we starting with notes or bullet points provided by the client? Or are we to do original research? Of course the latter is going to take more time than the former.
The bottom line is that the client has great control over the price of the job. By being prepared for and involved in the process, the client can reduce our time, thus his or her cost.
