I'd do some leg work on your own if possible to get ahead of the curve. Pull the seats, then wet/dry shop vac as much water out of the interior as possible, then use the Houston sun to your advantage: crack the windows a half inch and let the sun dry your car. I'd also rent an ozone generator to run in the car, which will abate the mildewy smells. For the motor, I'd pull the spark plugs, exhaust and turbo, change the oil, then cold crank the motor to blow any water out.
