I was quoted $2500 for civil engineering, then I clarified I was structural and the price went up to $5000 for the first year. After that it may go up based on your billing. That was for $1M/$2M.
Our billing rates at the office vary between $130 and $175 and I charge my friends/family $100/hr for anything with liability.
@Ultrafault has a good point. If people can find high quality engineering work for super low prices it not only undercuts your industry but they may not value your own personal time.
