Black Friday Add-on

First of all, I know this will require code modifications. Just want to know who and how can do this.

It would be nice to have a feature where a vendor can select if they participate in black friday and if so, the % off they offer. When black friday period comes, every vendor that has that option checked, has the % discount applied to their products automatically. Also showing in another category called “Black Friday Deals”

Anyone able to do something like this?
