Need a litle help with e-gold

I have a ptc site and after people buy an advertising package and they pay by e-gold i want them to be redirected to a page on my site.
I mean something like this:
-They order something at test.com/order.php
-After that they pay by e-gold
-And now i want them redirected to teest.com/order_done.php
This is just an example.
Can some1 help me with this ? I would pay him a few bux depending how much he will help me.
Thanks
