I need to implement Website Payment Pro (WPP) feature in my website. I just need a simple script that has all required information (variables) to be processed at paypal and it get response back from paypal. It shud be well commented. I can handle the rest. I am going to integrate it in my custom built shopping cart but your task is only to provide me such script.
The project is fast and I can offer $30 for this single script. Only serious bids are welcome.
