The sol B 100%wr bag and the solA wr box are mandatory... They can carry only small items, but luckily ore is small, and they are really cheap due to the size too...
Edit : also I am not in business right now, too much of a hassle, but diogene was selling them recently, at 10k if memory serves... Skilling plus the raw material cost will be higher if you do it yourself, so if your only goal is to get this armor, buy it...
Edit2: I am keeping my platinum armor, but I am trying to sell a set of electrum one, you can see it there:
