This may be a god time to get into social media, but also consider signage on the doors, on your billboards that are easily changed, internet banking messages, emails to customers, etc. If you haven't been using FB, unless you have a strong following who will see it? It shouldn't be a primary means but can certainly be used to supplement other notices.
