selling ad space

Hi all, I hope I am in the right forum for this question, apologies if not.

I would like to sell advertising space on my website, so I have been have a browse through some of the plugins available. The only one I could see that fitted my requirements was WP125 BUT after reading reviews etc. it would seem that there has been no updates or any support at all. That put me off.

Basically I was after a plugin that would allow people to click advertise here & for me to have a kind of ad management platform, choose how many days the ad shows for & after that time its taken down & either replaced with a blank or a new ad, the plug in could maybe take control of the payment side of things as well, so you set how much & for how long. Different size ads maybe. That partcular plugin was just for 125×125 ads but the option of different sizes in different positions may be a gd idea too.

Is this making sense ?

Thankyou in advance,
Richard
