What drives the cost
Work expected to take under a month has a median of $640, against $300 for one to three months. Part of that gap is built in, because hourly estimates are calculated from expected length. Fixed-price posts state a median of $220, while hourly posts work out at $4,900 on our estimate: 22 times as much. One likely reason is that fixed budgets tend to cover a small first step, while hourly posts describe sustained work.
