Or with woodcutting, get 60 WC and woodcut Yews south of Edgeville Bank.
Only problem with those two methods is that F2P is extremly crowded, so unless you're a high level in either of those two skills, you're going to have a hard time.
If you're wanting to make money with combat, I'd still recommend the Stronghold of Security. There's plenty of monsters there, which have great drops.
