Text Link Advertising Script

I require a text link advertising script similar to [login to view URL] for use on our own private network of websites to sell advertising space on our sites, and other advertisers websites. The type of functions we require is the same as what is currently available with Text-Link-Ads, so potential creators are encouraged to familiarise yourself with their system. Typically, the system should be able to display websites which users can purchase advertising links on, and to be able to sort by category, cost, PageRank, Alexa ranking, Domain Age, Language, Number of Backlinks The user should be able to obtain full information about the website that they are seeking to purchase adverts on. This information is a combination of user submitted information, and also Alexa rankings and Google PR - so the script should incorporate the capability to recover a websites/webpage PR and Alexa ranking, and to calculate potential advertising values using other metrics should be incorporated into the script. An idea of the kind of metrics needed can be added easily to websites' information A payment system is also required to take payment for adverts purchased. The ability to take payments (via paypal) and refund or pay advertisers via paypal is also required. The scripts is required to remotely display adverts on the advertisers website also, by means of a piece of code inserted in the advertisers webpage or website. The capability to operate across multiple platforms and programming languages is also required, depending on what system and coding the advertiser uses - ie, php, asp, or even a blog site using wordpress, vbulletin etc. basically the script is required to act as an intermediary between the webmaster selling advertising links, and the webmaster purchasing advertising links, and to be able to take the details from one, and display it on the other, via remote scripts which would operate on our own server. The ability to create user accounts, and also operate an affiliate payment system/referral system is further required. Potential creators should make sure they fully understand the requirements of this project before they submit a bid by explicitly stating this in their bid details. If your bid details do not explicitly state you understand this project, it will be ignored and rejected. Any other questions can be submiited via the pm system.
