Advertisement Plugin for Yourls Shorten Url Script?

Hi,
Just registered here and hope gurus will help me in my issue as I'm totally a newbie in php/javascript.
I installed Yourls (Url Shorterning Script yourls.org), its working fine. But I want to add a feature which can show an Advertisement page for 5-10 seconds before redirecting user to the destination page.
I have read on their (Yourls) site that plugins are best way to add any feature. But unfortunately, my knowledge of php is zero.
I will be very grateful if any one can help me..
Any suggestions or advices are warmly welcome. :)

Their site was suggesting the plugins page directly. However, there is no plugin for advertising.

Since you know no PHP, then you'd basically be asking us to write the whole thing for you. You could post such a proposal in the Open Positions (Jobs) forum.
