Ok, I used the "search" function to get answers to a bunch of questions I had about de-thatching. Questions like: 1. How well does the JRCO front-mount de-thatcher work? 2. Best time of the year to de-thatch? 3. Benefits of dethatching vs. aerating? 4. What to be careful of (sprinkler heads, etc.)? My question is, "what can I reasonably charge?" The info I got from my search ranged from $5/1000 sq.ft. to $40/1000 sq.ft. Some other answers went from 2X what you would charge to mow and trim to 6X that amount. I'm lost...would someone help me???
