A really good way to make money

Hey guys, if any newcomers are wondering, "Good god It's going to be a pain in the butt to make money on here", Well I know a few really good money making tips. First: Kill goblins near the river in lumbridge. They drop staffs of air which sell for 600gp a piece. You'll probably get one every 5-9 kills. Second: Chop oak trees behind the general shop in lumbridge. Oak logs only require 15 woodcutting (which doesn't take long to achieve) and each log sells for 8gp. Now I know that may not seem like much, but multiply that by 28 (full inventory) and that's 224gp. And it's at a much faster rate than killing goblins. (that's an alternative). You can also get clue scrolls from killing 5-9 goblins in lumbridge as well. Those are the only ways I know so far that's good for new players. Good luck
