web directory payment system

We are in the phase of creating a web directory for business using a software package called power seek. The software package can be viewed at [login to view URL] What we are aiming for is for the clickbank subscription payment system to be included in the software package so that members can pay for their information to be displayed within the website directory. The payment system will have different payment classes, if the customer meets certain requirements then they will have a reduction in the price, this will therefore create a payment scale. So we require template for the payment section of the directory payment class the person has selected. The template section is contained within the control panel for the powerseek software. Also any changes to the sql and database used for the information, so that we can perform searchs to determine who has paid and who hasnt and what level they are using. For a qualified experianced coder/programmer or team, this will prove to be a stright forward and resonable task. Only resonable offers will be reviewed. thank you for viewing and evaluating the project
