Emergency plumbing

I have an emergency plumbing issue. The one bathroom in the house needs major repair. The main line to the bathroom leaked. I was completely unaware, this in turn caused extensive water damage. The bathroom is inoperable at this time and part of the floor is too dangerous to walk on due to the water damage. Anything you can help with will be greatly appreciated. I live on a fixed income through disability each month and hiring a plumber could not happen with the income I make at this time. Thank you all for your support.
