Recommendations for office cleaning (special)?

So the first rain of the year was last week, and there was a construction project ongoing on the roof.

I bet you can guess that there was a huge ceiling leak that mostly hit my office. For about an hour, water streamed into my office that morning. The construction crew set up de-humidifiers and retarped the roof to stop the leak, but it does not seem to have been enough to avert disaster. I'm pretty sure I'll need help cleaning up the mold, dirty walls, and stinky carpet now. That's not going to be a sustainable work environment for me until it's been taken care of.

Does anyone have advice for who I should contact about getting that cleaned up and safe to inhabit once more?
