"Typical markups in law firms or consulting firms might be 4x, e.g. a worker making $50 per hour would get billed out at $200. The same person on a marketplace might raise their rate to $75 to compensate for utilization, but the end price to the customer might end up at $85 – $95 per hour."
Doesn't work for IT same way, obviously. Luckily the average quality matches the average price + time wasted.
