In my opinion I would not mention anything about price until you were standing in the yard with the customer face to face. People could interpet low price a lot of different ways. Some may think you are low-balling the competition and do less than average work and you're just trying to get #'s. One other thing, never give an estimate over the phone, if you do make it a broad range price like 50 ---75 bucks. If you say my average yard is $35.00 they will expect you to cut their 3 acre farm for that! No, leave out price, everyone knows you have to charge. Stick to the good points. Here is a statement I put on mine under the heading "ABOUT US" the last sentence is " and the owner is always on the job site". This works right now, there may come a time when it doesn't. You are a consumer, what do you look for in an ad? Be original.
