The Ways I Am Putting Are From The Best To The Worse:
1) Cut Yew Trees (Level 60 woodcutting Is Required, but It Is The Best Selling Item)
2) Mine Silver/Gold/Mithiril/Adamant/Rune (Silver is Low Selling)
3) Eyes Of Newts (You can Buy Them For 3 coins in Port Sarime's Magic Shop, And Then You can Sell Them For 100 Coin At Grand Exchange)
4) Runecrafting (High Levels Make More Money)
5) Sell Sword Fishes/ Lobsters...
Teak Logs.
