GIM alt for gp?

Our gim made an alt recently, since we’ve had an open spot for a long time. Eventually will use it for bigger things but in the time being does anybody have any ideas for low intensity ways to make gp on it while I grind slayer/raids on the main account? I want to make 40m for turning my mahogany logs into planks. It’s okay if it’s slow I just want something low effort that doesn’t need constant clicks like thieving or agility pyramid.
