Wear a collared shirt. If your wearing dingy tshirts that youve mowed in all day to do the estimate good luck getting $50 for 6k sq ft. You dont look the part. Yes you look like you work hard. But I think the general public sees landscaping guys as dirty, wayward people who are uneducated and hard work is their only redeeming quality. People judge at first glance. Its human nature. Sales is all about psychology. First impressions MATTER! Wear a collared shirt. And brush your teeth.
