PPC XML Feed Setup

Hello, I have access to a PPC XML feed, but not directly. I point a sub-domain like "ads" to the provider's IP address. I cannot figure out how to fully integrate the feed into my site. The provider has only given me a document with some variables to use, which I will send to you. Here's what I need: 1. One simple domain name parking template, examples: [login to view URL], [login to view URL] The template must have a working search box and the links, when clicked, must display the related ads (the template should be very simple, nothing fancy, doesn't need graphics, plain and two colors is fine) 2. When someone visits a non-existent page (404 error) I would like ads to display related to the keywords in the URL. For example, assuming the URL "http://getafreelancer.com/music" doesn't exist, I would like there to be music ads displayed. (this should be as easy as adding something like "ErrorDocument 404 /display_ads.php" to the .htaccess file) I need this completed within 24 hours. I will deposit the winner's full bid amount into escrow and release it when I can test the code is working on my server, which has PHP 5 installed. Please ask any questions before bidding. I can send more examples etc. By placing a bid, you must be able to complete this project to the above specs within 24 hours.
