Now, you have thousands of free document templates that can be turned into web forms. What you need is, open MS word. Then you will need to go to your title bar and move to file. Here you have several existing templates to choose from. You can choose anyone among them and modify them according to your needs. Apart from changing the forms, you can start with a scrap or, blank template.
Perhaps a good subtitle would be, "How do I earn a bit of money when I learn how to create a business letterhead in Word." Because you can always find ways to monetize your knowledge (that's what knowledge is for, isn't it?).
