Depends on what we’re working on together. Are we searching for and applying your brand voice? This typically takes three or four weeks. Am I writing copy for your website? I’ll need a week or two for a light landing page and between three to six weeks for more content-heavy projects.
That being said, I always put together a roadmap of the project and give it a fixed deadline before we start. These details come as part of my proposal, so you can decide up front if the timing suits you.
