I find commercial guys in my area easy to deal with. If their boss isnt mad at them over price or looks, they ignore you and send checks willingly enough (if not quickly). I work for alot of big companies, so I deal with mostly regional supervisors, and less business owners. They have about two million things to do they think is more important than talking to you. I like my residentials, but they require alot more time, both on the job, as well as talking them up. I also put alot of faith in yearly contracts. One set price every month, rain or drought. Commercial guys love it, where residential are more willing to take the risk, meaning you might be without income this time of year. I keep a healthy mix, so in the spring I have those residentials paying for 6 mows a month, and in the dog days of summer I still have my commercial guys paying the bills.
