BuySell Ads:
according to this network you can select your own ad cost and you will get the price what you have selected. You can place as many ad units you can and clicks does not matter to these ads units. Just you have to make ad space by putting the code of BuySell Ads on the desired locations.You will receive earning on monthly basis or whatever you had set the price plan. but it is tough thing to get approval..your website should have a high traffic for this approval...hope you understand.....
