coupons website with linkable banners on refresh

I would like someone to built a website that will feature web-based printable coupons. The site should make it easy for a user to search for coupons based upon neighborhood – zip code, type of business/categories or name of business. Clicking on a specific coupon "offer" should enable the user to print the coupon, or be able to select multiple coupons and print them all at the end, as a sort of “add to cart” idea. Users should also be able to email the coupon (to themselves and/or friends).. There should also be banner ads, again specific to the area and region and state, these banner ads should be random based on refresh button. In other words. I want about 10 to 20 image banners of businesses that would randomly post on site based on refreshing. For website design look, I would like to be able to embed flash, background music, video... Backend will be managed in a secure "User Account" area. Merchants will be able to log-in and create, edit or delete their coupon offer in real time. Coupons entry area should be a wysiwyg idea with text and images. Should be able to set time limits and coupon printing limits (based on IP) , when their coupon comes into effect, and create several coupons for months ahead that start and end automatically. Merchants will also be able to pay their bill to the site by credit card etc.. Merchants should be able to see how many views their coupon has received, how many times it has been etc.. Other requirements that providers will need to know: The site should have a secure Admin area to set up new merchants within the system. Specific expertise/background that I am seeking: This project requires experience in database-driven websites, I am open to ideas from joomla, osc, wordpress, drupal etc... If someone has created a site like this before, it would be a great bonus to see this in a portfolio. Additionally, if you have good developer, graphic and design skills you will have many more project and extended job in the coming months once the site is up. I have many more folks that may be interested in this similar projects. So this could be at least a handful of new projects for your company if not more.
