Ok, I have a website that gets around 2000 unique visitors a day, via Google. This is steadily growing as more articles are added. Adsense isn't really cutting it, as it's not making enough, so I'm wanting to find people to pay me for me to list their advert/banner instead. But I'm not sure where to find these people. I've tried showing a 'Advertise Here' banner on pages which hasn't worked. It's a fact/education type website, so the subjects vary tremendously. One article might be facts about France where another might be foods that contain a lot of vitamin C, so very random. Anybody got some tips to help? There's a website called buysellads.com but they wanted a stupid amount upfront from what I remember.
