Text link ads script wanted

I am looking for a text link ads script to offer a service like [login to view URL] or textlinkbrokers.com. There is a script at [login to view URL] but that has a lot of bugs and does not meet the requirements. I would need a more professionel script. I prefer bidders with experience in programming that kind of script and examples of previous work, best would be a already working script, ready to install.
