Why do people charge 18+ gp/xp for construction exp with mahogany tables when it's 450-550k an hour. Literally 2x the amount for prayer and a lot less work since butler. People charge less than 10gp for prayer. I got quoted 160m for 63 to 95 prayer 8m exp which if you do bare minimum exp an hour from what guide says it's 400k an hour which is 20 hours. So 160m to do 20 hours of work.
