Essentially, you have two options:
(1) Contact a local certified arborist for an estimate to remove these trees as the probability of finding someone to PAY YOU to remove your yard trees is nearly zero.

(2) Contact a custom sawmill operator to determine if they are interested in your particular trees (take photos). However, it is important to remind our readership that the vast majority of custom sawmill operators deal with logs, not standing trees -- and especially, not standing yard trees in urban areas!
