Click on the Dashboard in the top-left corner.
Click on New.
You have three different options. You can create a new page from a template based on your sales use. If you have very similar clients, you can start from a page that you've already sent out. Every time you send a page, a copy will go to your history tab and you can edit a page from there. If you ever need need to step away from your computer, make sure you save a draft. Then you can come back to the draft page and start working from there.
