Which isn't to say that any given lawn care service is not viable, but the whole "we're doing it differently" would indicate something more than, you know, setting it up online.
That's just me and I'm a cynic. But I feel like if you're going to take a stab at a paradigm shift in an industry, you should aim higher than this.
Keep in mind, this is precisely how I found and set up my lawn service, which is just two guys. :shrug:
