After talking with these folks, we agreed to pay much more to have these folks deliver & blow high quality bark consistent with our needs. That was a mistake. We specifically asked to get large (coarse) bark nuggets - not fines; not ground up wood or lumber scraps; not rock or organic debris. Guess what? We did not get what we were promised. I was also concerned that the blower might leave bark in my lawn. I was assured, however, that that wouldn't be an issue; they would cleanup anything. Yeah, right. I just finished picking chunks of lumber, err "bark" as well as rocks, err "bark" out of my lawn. I'm too irritated to even address the fact that I asked for a a 5 yard pile of bark and was provided and billed for a pile that would fit in the back of my vehicle. Which, if I had a typical 5 yard dump truck would be fine. But, I don't. Lesson learned.
