Towing advise

I am in the unfortunate situation of helping to clean out my grandparents house to sell after a sudden passing- there are two cars, a truck and a town car that no longer work but need to be taken to my uncles lot so we can finish cleaning up the house to sell- anyone have any suggestions where I should look? They are located in Farmington and I should mention the cars are on a pretty steep driveway, any help would be appreciated!
