If the wood is falling apart when you pick it up. It’s probably done-zo. Get a good maul and metal wedge and try splitting it. I would expect the wood that is resting on the ground would likely garbage, depending on wood type and if it was able to dry out. Everything else may be good to go; once again depending how old, type and if it had a chance to dry out.

Honestly don’t get someone to do it for you. If you are physically capable then do it and in the process you will learn the difference between crap wood and good wood.
