I am selling 3 300 x 250 banners on my blog. Each banner is 300 x 250 and 2 are located in the side bad and 1 is located in the footer beside the tag cloud and top posts. I am selling each of these banners for $3 a month. My site is currently getting 16,000 visitors a month and 160,000 hits and over 80,000 page views. Please pm me or post if you are interested.
