A Deal of the Day website w/ Magento

This project is for a Deal of the day type website. If you are not familiar with the Deal of the day websites, Go visit [login to view URL] and it has a list of DOD websites. I would like the design to be clean and fresh. I will be providing with the design that I have created with Microsoft Expression Design, However; I am open to do another design. I am really interested in Magento. They are an Open source that offers many applications for ecommerce. It is also less work on the developers because you dont have to reinvent the wheel. I want only One product a day. after that product is up for the day it should go into another webpage titled "Previous deals". it should give the customers an option for a chance of the previous deal. Products should also have the option of switching to the next product when sold out. Also, at check out I want there to be an option where the customers can donate from $1-$5 to the monthly charity- each donation should be recorded as this money is also part of a raffle.
