I got a guy that asked me for a quote and a month later he had a mow rig. Now I know he just wanted to set a price. Now he got his price but nothing else. Had he walked up and just told me what he was thinking he would have gotten alot more than a price. I'm not worried about him taking my work so he could have learned a ton that would save him in the end. But he wanted to be undercover so now he can work it out.
I would get you some books and learn your local plant material, pest, and soil issues. You cant sell nothing. If you can walk up and sound smarter than the other guy, then you win. Even if he does every thing you can talk about, your service sounds better
