We contracted for weekly lawn-cutting service, but they came only sporadically. The lawn would grow to unreasonable lengths before they'd come again. We got a quote for a big job in early August and gave the okay, but they didn't start work until mid-October and then only finished half the agreed-upon work by early November and expected to be paid for the entire job.
Pros: None to speak of
Cons: Never know when they'll show up
