PHP coder needed to Modify a Script

I have a traffic source which sends traffic to my blog, however what I do is before the traffic gets to my blog, I pick a random page from the blog to send them to so what happens is this Traffic Source > PHP Script > Random Post on Blog However the way the script works is it sets the referer as the PHP script so the owner of the blog can see the referers coming from the PHP script which I want to stop. I need coder who can come in and modyfy the code so it wil blank the referer but also pass on a magic value to the blog so it knows the traffic has just come from that script. Its probably a very simple job but i need someone competent enough to do it.
