How to Setup a "Buy A Day" Sponorship

I am evaluating carts and one big feature we need is the ability to setup a “buy a day” sponsorship for the site (a non-profit). They want to let people be able to buy a site and have it display the company in the a header box on the site. So it would be the same price for each day but only one person/company could buy a day and then that day would be unavailable. It's a bonus if there is a calendar function to pick a day but I don't think that is required at this point.



Cas CS-Cart do this, and if so, what is the best way to set this up in CS-Cart?



Thanks,

Andrew

Am I correct that you want to sell banner ad placement?
