There is lots of information online to teach you how to write content for your website. I will suggest the easiest way is to visit other similiar websites, look at pages that you are also planning to have and get some ideas. This is by far the quickest way to gather your thoughts and help you organize your information. Speak from your heart and make it as personable as you can. People like to buy and do business with people they feel they know. Let them know who you are.
