1. There are BILLIONS of Websites and blogs. Use a search engine like Google to find Websites and blogs that interest you. Now start surfing. When you find one you like and/or that you know has a good amount of traffic, contact the Webmaster (there's usually a "Contact Us" link in the footer or header of most sites) and ask about advertising on their site. You might be shocked at how cheap you can get banners on some fairly high traffic sites.
