We require a simple set of code written in as3 and php. It should allow a SWF file to post a payment request to Paypal in a separate window, then receive the confirmation back from Paypal without closing the SWF.
This is NOT just a 'Buy Now' button for flash, it's really important that we complete the payment cycle without navigating away from the page that the user clicks.
An example of the sort of thing we're looking for can be found on a video in this page:

No graphics / design are needed beyond simple test buttons and text field that prints out sucess or failure.
No hosting or additional PHP is required.
We look forward to hearing from you.
