It is just an easy job.
The hole was slamed by a basketball. So this hole has a good size. Build a new "ventilation-system" and fill the hole with a fan in the right size. It is a little bit more expensive than two posters, but a good looking, new-technical solution.
It should be easy for you to find a fan - you have a fan-forum.
So just look around for a smart girl and then you will
have the sexiest door alive.
