Hello,
Adding quality content to your one page website is no problem. There are a ton of article directories on the web with loads of content on almost any subject. As long as you keep the author's (bio box)name in the article you can post it on your one page site for free. If you want to take it a step farther you can place adsense on your site for additional income.
Regards,
Paul H.
