A quick update: I emailed all three suggestions mentioned here, plus one other landscape contractor in West Seattle. Le’s replied to me within two hours. One responded six days later. The other two didn’t respond at all. I realize that landscapers are busy now but, if you advertise your services, the least you can do is be responsive to inquiries. In any case, I’m happy with Mr. Le’s proposal and his crew has already begun work on my yard. Thanks for the suggestion, timeslid.
