Hope this helps. Info from 2007 Runescape Wikia.

It's a good start :). However, if I may offer some constructive criticism, have you considered fleshing it out a bit more? Add pictures, ways to get leather, alternative methods for different budgets, etc.? Hopefully there are more viable ways than spinning close to a million flax!
 
As it stands it just looks like (through no fault of your own, BBCode doesn't support tables here) a less cleanly formatted version of 2007 Wiki's table with a word or two added, but I'm sure you can improve it if you set your mind to it.

One thing you could add to this would be how much each set costs
