Loss of Livelihood

My parents operate a small trucking company and they recently lost their entire means of livelihood in a fire on Sunday, December 13th, 2020. Only one semi remains and the rest was destroyed (work materials such as tires, chains, platforms, and tools). There are many expenses to come regarding the clean up of their lot, repairing the neighboring lot, paying back what was owed for the semis lost, and other expenses. The majority of what was lost is not going to covered by the insurance. It would mean a lot to us if you could help us any way you can. We also seek professional advice to know what further steps to take regarding insurance and investigating the cause of the fire. Thank you.
