Help clean toxic environment for my dog & myself.

After renovating bathrooms in my apartment complex they left my apartment toxic to live in. My dog and myself have been sick ever since. 60+ years of dirt and rodent dander was dropped in my apartment like a nuclear bomb. No precautions were taken for the drywall dust as well. Housing is not responding to my pleas. My apartment needs professionally cleaned so my dog and I can have a safe place to live. I’m currently staying at a Super 8 until tomorrow morning. After that we will be homeless and sleeping in my car. We cannot live in atoxic environment. I would very much appreciate any help you could offer. Thank you.
