I have a very new site that is doing well, and I was wondering how much traffic you need a day before people would want to buy links on your site, and if they would how much do you think they'd be worth. my site has about 5,000 unique visitors a month.
I would go with AdToll (see my sig for link) to sell banner ads on your site. But if you want to sell Text ads you should go with AdEngage.com. AdToll has an auto pricing feature so you don't need to know exactly what a good price is. You can adjust it if you think you are charging too much or too little. Both sites add you into their site directory where advertisers look for sites to advertise on. The best part about them is they have RON ads that will show if you haven't sold enough ads to fill your space.
