Add publish status to Pages

We have a client who like to run competitions and give away hockey tickets etc. What I would wish for is the ability to set a time limit on the published status of a page (like blog articles) under the page properties and then have a redirect page to go to outside of that time e.g: Competition page is named something like “/competition” and then there’s a separate page called “/competition-closed” that contains info like “Thanks for your interest in this competition but it has now closed” which is redirected to.
