Blogtap.net, a great resource for bloggers receives roughly 500 visitors per day (can show google analytics proof). Ad sizes / placements are negotiable but we are currently looking to sell 125 X 125 buttons in the sidebar. Price: $50, non-negotiable. The first month of advertising is FREE. Meaning you will not pay a single dime until after the first month. Payments made via paypal subscription. Check out some of the articles on the site if you have any questions about the nature / quality of the content. It's a hell of a deal. PM if interested.
Well, since I haven't gotten any responses I'm lowering the price drastically to $35 per month. PM me if interested.
