JW Player overlay advertising implementation

I need JW Player to be modified in order to accept preroll and overlay text/banner advertising from a third part company. ( Without using Longtail solution - this is VERY IMPORTANT ) The advertising will be provided as JS in the next format: <!-- Begin Joybox Code --> <script type="text/javascript"> jb_code="xxx"; jb_skin="120x400"; jb_width="120"; jb_height="400"; </script> <script src="[login to view URL]" type="text/javascript"></script> <noscript> <a href="[login to view URL]"><img src="[login to view URL]" border="0" /></a> </noscript> <!-- End Joybox Code --> Please pay good attention to what I am asking, because is the third time when I post this project and the bidder is bidding without reading the project details. If you have any question please feal free to ask. Hapy Bidding
