A friend of mine here near Cleveland is having professionals cut down a Black Walnut tree down in his back yard. I beleive it is a decent size but have not seen it.

3 questions.... 1) is it worth him have them cut it down and then try to sell the wood for someone else to saw and dry?

2) If so, what size logs should he ask the tree peopel to cut the tree into?]

3) how should he price it?

Thanks for any and all advice
