Get your fishing to lvl 40 and fish lobsters in karajama.Now sellat 306 gp a lobster.Or,get your combat lvl to over lvl 28 and buy a brass key at the grand exchange and go out and head for the barbarian village.On the way,look out on your map for a small house witha door.You need the rass key to get in the house and and go down the ladder,and kill the hill giants (lvl 28) and take their bones and sell them at the grand exchange for about 389-400 gp(i have forgotten what the priceis)and now,you are rich(after about 500 trys)if their is any better ways to get non member money,then comment on this,thanks
