What drives the cost
Work expected to take under a month has a median of $300, against $12,500 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 $250, while hourly posts work out at $4,000 on our estimate: 16 times as much. One likely reason is that fixed budgets tend to cover a small first step, while hourly posts describe sustained work.
