Trench, build the lines, back fill.
A good crew can do about 3 commercial sized laterals a day (about 6 big zones, maybe a whole small house if you are working quick)
ON a house I like to do the mainline one day, and the laterals in the next day or two.

Never trench much more than you need in that day, you'll end up cleaning it out.

I think Murph has all that figured out. He'll be OK.
