Build a Custom Layout Update for Magento Product Page

I currently have a live e commerce website built on a Magento 1.6 community version. - A new custom layout for our Product pages needs to be created. The best and easiest way would to create a 'Custom Layout Update' for our Design section in the product attributes page of Magento. - The products that will be on this new page are 'downloadable' free resources. - The current 'Add to Cart' button needs to be changed to a 'Download' Button. Which has the function of downloading a file. The functions of the shopping cart need to be taken away from this product page. - The price must be taken away from not only the product page but from the information underneath the category page image. - The page needs to hold a large image of the downloadable resource. - The page will also need to feature a 'BACK' button which actions to go back to the previous page. This job needs to be done on our Custom layout which can be given and accessed by our FTP. The job is very small and needs to be completed in 1 day. The best option for this would to create a 'Custom Layout Update' for our template design. I will be back here in 8 hours and will choose a winner for the project, so you must be ready to work in 8 hours from now. Good luck!
