For Sale: Black walnut trees for removal

My mother has two black walnut trees in SE Portland that need to be removed. Both are fairly easy to access and away from buildings and power lines. Is anyone interested in harvesting them for their lumber in exchange for removal, cleanup, and stump grinding? The larger is 110" circumference, 3’ diameter, good 60’ tall. The smaller is 68" cir, 2’ dia, and approximately 30' tall.
Any information or offer would be appreciated.
Thank you,
Paul
