Magento Custom Programming

Hello, I am a e-commerce platform programmer. I have a custom script to be written for Magento where it shows a dynamic timer with sale ending time on both product page and category page. I am new to Magento and due to its steep learning curve want to outsource this small bit. If a product is specified as special price it should display this timer which counts down to sale ending time. The timer should blink every one minute like in bidz dot com. All days rounded off in hours. i.e. 3 days will be rounded to 3X24 hours and so on. This is hardly 6-7 lines of PHP but i have no idea where to make the changes. I want some one with knowledge of ZEND architecture and familiar with Magento. The code should be implemented on your own cart and instructions of installation on Magento Version 1.3.2.2 should be passed on to me to consider this project to be completed. You will not be given access to our live site. Please bid reasonable. Questions will be asked regarding Magento so please dont waste your time and mine if you are not familiar or doesn't have your own Magento installation on your server. Idea in attached files. New freelancers will be given preference but should be able to answer my questions regarding Magento in PM. Thanks
