I'm looking for you to write the copy for a Sales page for an app. There is already a website that has all the information about the product. But I would like a landing page built for the app to be hosted on a separate site. The current content isn't great and I'm looking for a casual / light voice. The app will be related to SEO, Website Optimization and the copy should be focused around how it would benefit a marketer. I'm looking for someone with a history of writing sales copy.
