Lots of fans. Open all windows when you can to let moister out. If you have a/c, I'd run it when the windows are closed. Normally you can rent de-humidifiers but I'm guessing everyone available has been rented. Remove anything that maybe saturated with water- i.e. carpet, drywall. I've got a carpet fan you can borrow if you'd like. The biggest thing is to get air exchanging ASAP.
