Below is a list of companies that pay you per click. They have just revamped their site and increased their payout to a tiered scale ranging from 10 to 17 cents per click. Unfortunately they have scrapped their refferal program. Banners are pulled from their server which makes setting up very easy. With over 300 pay per click, commission and impression programs to choose from, CJ is one of the best.
Links are easy to setup and their site is very easy to navigate.
Very, Very Good. Have heaps of banners to choose from and can pay up to 20 cents per click. They also have impression and commission based programs. Has some javascript enchanced banners that get good click rates. Worth a look.
