Just hired my first crew for lawn installs, now what? Newbie landscaper rant

Been solo doing small yard cleanups and basic mulching jobs with my Stihl backpack blower for a couple years, but finally pulled the trigger and hired two guys to help with sod installs and edging. Now I'm staring at scheduling headaches, like how do I make sure they don't screw up the irrigation lines while trenching for new beds? Someone in the Lawn Care Professionals FB group mentioned using Jobber for tracking hours on mow routes, but I'm worried it'll be overkill for our scale. Also, training them on proper aeration without ruining the turf is stressing me out already. Saw a post on r/landscaping about a guy who lost a client over uneven gravel paths, don't want that. Watched that Mike Andes video on scaling up and it got me hyped, but reality's hitting different. Any tips from vets on keeping the first hires from turning into a shitshow?

you have to train them. at the end of the day if they know what they are doing they wont fuck up
