What is Black Walnut Worth?

Okay, in the wake of Hurricane Sandy, one of my dad’s black walnut trees was uprooted. It is a rather large tree, being about 2.75 feet wide at breast height (about 5’) with a trunk almost 30 foot before it disseminates. Some prospective farmer in a fancy pickup truck spotted it, and offered my dad free on the spot removal, and nothing more. I believe it has more of a worth and even presents an opportunity in some cases.
Id love to see this prime piece cut in 8–9’ sections and stored to season… any idea of the cost, or a method in which to move the sections. It just seems like a worthwhile woodworking project in the future.
Thanks!..
