This is my first year to take of lawns-yes, am licensed. I have about 20 yards now, but most of them have not been well taken care of. In fact, some are just downright BAD! My questions are?<p>1.Do you charge extra for the extra trouble of going back several times to get rid of these difficult problems?<p>2. Does anybody have a contract/or brochure stating what you will and will not be responsible for?<p>Any advice is greatly appreciated.
