Good post. Too many contractors get fixated on one number that they feel for whatever reason they must "get." Or, they throw prices around with nothing to back them up. Your point of "know your costs and the point that it is not worth it" is the best advice I've seen on here yet. Charles Vanderkooi teaches to know three prices (I can't remember exactly what he calls them)......price with hoped for profit, price with profit and basically a price that covers cost with very little or no profit. This gives you the information you need in negotiating price, if that becomes an issue and right now, it's an issue for everybody.
