Modify Php design and Mysql database for website page

We have a current working website in Php using Mysql. We need to change the layout of our product details page. What we need you to do is to change our current default product template design (how each of the products that we add to the website is displayed) to the new design that we would provide you. this would entail changing the php code of the current template, and adding new tables in the current mysql structure. the project is not that difficult for programmer experienced in php/mysql. we are looking for long term programmer/company so that we can use you again as we frequently change/update our website. please bid only if you are successfully setup in rac with good feedback and if you can make changes as we supply them to you. this is a rush project, so we are looking to assign this as soon as possible. once you make your bid/comment, we would provide you with the details of the changes as we require, as we do not want the details to be disclosed to everyone. thanks
