You should maybe have a start on 100k and 30 smithing (The blurite sword's should give you from 1 - 29 I think.) When you got that, Buy like... some iron ores and double as many coal as iron ore. Then smelt it to Steel Bars. Go Back to Grand Exchange when you are done and sell your bars. You will get money and some smithing Experience. Good Luck if you wanna try it.
