I was just informed, by a family friend, that another contractor has given a price of $147 per tree on 6 - 7' Green Giant Arbs. This price includes a 1 year warranty. My estimate was much higher. Granted, I was using 2 - 2.5" Carpinus. However, the price I pay for both species is exactly the same. Am I wrong for wondering how/why this contractor has been in business for over 20 years, or are my prices extremely high? After adding my labor costs, plant material, compost, fert, mulch, etc., I was under the impression I was still cutting him a deal.
