looking for PPC system/software

[joesearch]

Hi,
I am planning to offer PayPerClick advertising on my own portal/website. But I haven't been able to find any good PPC software which allow me to offer this to my advertisers.

Does anyone know of any PPC system software for running your own PPC sites?

Thanks in advance.

if you need to go cheap (which may mean you do not have adequate resources to market the service you are trying to create) you may want to try
http://www.smarterscripts.com/smartsearch/ for about $100

if you can afford a more expensive script, Hyperseek
http://www.hyperseek.com/index.php/purchase/
costs about $300. if you need further modifications and the like you could buy the source code version for $2000.

I usually recommend creating vertical content portals and then bolting on a PPC service instead of trying to start a PPC service from scratch. if you get lots of traffic you may also be able to partner with Overture to sell PPC listings they would deliver to you via an XML feed.

I think many people use bridalclicks as an example of a good vertical PPC site.
