This guide assumes that each trip takes 45 seconds. Your profits may be higher or lower depending on your speed.
The Woodcutting Guild in Hosidius contains a sawmill which is located significantly closer to the bank than the one near Varrock. This allows the player to make even higher profits by creating planks and selling them on the Grand Exchange. Each plank requires one mahogany log and 1500 coins, and each trip takes approximately 45 seconds and creates 27 planks.
To start, withdraw your cash stack and 27 mahogany logs. Run to the sawmill, right click on the sawmill operator, select "Buy-Plank", then "Buy All" underneath the mahogany logs. Run back to the bank, deposit the planks, then withdraw another inventory of mahogany logs. Sip a stamina potion as needed in order to restore run energy. You can quickly sell your planks by instantly buying a plank on the Grand Exchange, then selling all of your planks for slightly lower than that price.
