An interesting concept. And i have a couple customers who like this way and have asked me to do it. I show up and i take a look around plants and hedges better look prestine, shrub beds better be clean and weed free, walkways better be clear and the grass better be cut perfectly.
This is a nice concept and i love the money generated by it, Unrealistic to the small business owner trying to make a name for himself and succeed. I cannot be picky with my customers as i have two children a Wife and a home i am buying. I am 23 and i do all this. I would have 3 customers left if i changed to your way and that just wont cut it.
I am a Lawn care guy I mow blow and go. And then if you need some landscape maintence (which is what you are not a landscaper you do not install landscapes) I will bid the job that you requested haggle with you a bit come to an agreement and then do said job. I will never do anything without talking to my customers first as what they want is what counts not me..
Also i would never go months without talking to my customers :/ that just doesnt make since I will throw them a courtesy call at least once a month if I do not run into them. Make sure they are happy with my work and if there was anything i can do to improve. OR if they need some maintence.
I like the way you run your business and i am glad you are successful there is really no point in arguing how we run our stuff because i am not you and you are not me. I cannot do what you do nor personally would i want to.... Kinda sounds like a lot of work. Some days i just like to Mow blow and go home and have an easy day.
