I think there might be another thread on these.
My opinion - based on a very recent experience, I will likely not take on projects that involve getting things out of pallets, back rooms, stock rooms, etc. I am now of the mindset that some of these things should be done by people who are covered under work comp insurance, not people on a one and done flat fee project.
It is hard to know the condition of every store - some stores might have the hoses out already or pallets already, some might not. It could wind up being a very easy visit, or one that requires some major elbow grease on your part.
