Bill,
With fresh water & no pre-existing water or mold issues an in-place dry down would save you some headaches, but time is of the essence. In as little as 72 hr the water can be as dangerous as raw sewage, unless you remove the conditions that allow it.
If your around kc, there is a supply house down there (interlink or aramsco) that would let you rent the proper equipment to dry it yourself. Some rental shops keep a supply of real drying equipment.
1. Reduce the humidity below 30%, lower the better. You can contain the area (close doors, block return air vents, 6mil plastic) to facilitate using smaller equipment. 15-20% is a good target for drying environment & removes one of the conditions required for mold to grow, high humidity.
2. Apply pressurized air movement. Axial fans or snail "carpet turbo dryer" style produce great results. You'd need at least 1 per 10' of drywall, 1 per 5 being better. The equipment we use to do this is low amperage, this allows designing the system to fit the available power/circuts. It also removes one of the conditions required for mold to grow, stagnant air.
3. Heat it up! 90-110 will dry it faster & remove one of the conditions required for mold to grow, a temp between 68-86f.
4. Leave the lights on. Not kidding, many types of microbial growth need darkness to grow.
It's not to hard, & your a smart guy. It definitely beats removing & replacing when possible. If you use a system as described it will be bone dry in 3-5 days. Those outfits may rent you a thermal imager or non penetrating moisture meter to asses & track the progress. If you have vapor barriers to dry through you want to exceed those #'s
