What drives the cost
Work expected to take under a month has a median of $500, against $12,000 for over six months. Part of that gap is built in, because hourly estimates are calculated from expected length. Fixed-price posts state a median of $500, while hourly posts work out at $5,200 on our estimate: 10 times as much. One likely reason is that fixed budgets tend to cover a small first step, while hourly posts describe sustained work.
