My friend has equvilant stats as you. He goes to barrows alot and if youre fast with the chest, i.e he uses only ice barrage and doenst get killcount in the tunnels. He does about 60 chests a trip and each chest costs him about 30k, but the speed pays of for the huge rune costs. He is using battle robes and sol to save rune costs. Last time he went there he earned 12 mil in 3 hrs. not to bad, but you have to experiment with methods and you have to have some sort of luck.

 

Another thing you could do is to go trio to Kree'arra
