Does anyone know of a salvage company in the Eastern Shore area of Mayland? ...
I'm not as familiar with options on the Eastern Shore but Baltimore, only a couple hours away, has some good options. Some will come pickup donations.

Also, The Loading Dock http://www.loadingdock.org/ is a non-profit salvage group who takes donations. Not sure if they pick up or not but their mission is to intercept materials bound for the dump and make them affordable for those who need them.

If none of these groups work out for you I'd bet they could recommend a place closer to the shore.
