You stated you wish to create

Helm Lardar:"Second, you appear to OSRS gold have some odd goals for a non-member." Anyone who's confused with Shree Sairam's goals: the stats desired are almost Salmoneus' stats. That's why at first glance they appear so perplexing. To Shree Sairam: If you want to get money in Runescape, what you want to understand how to earn money with skills (fishing, mining, woodcutting) and also to realize that there are money-losing skills (cooking, smithing).

You stated you wish to create and market mithril sets (6,223 gp) to purchase a Santa Hat (100.6 million). However, smithing is a money-losing skill. A mithril set needs 13 mithril bars. Or if you prefer, 13 mithril ores and 52 coal. 13 mithril bars * 1680 gp each mithril bar = 21,840 gp 6,223 gp. Selling mithril bars, mithril ores, or coal are better money-making than selling mithril full collections.

Stronger money-making from the Grand Exchange comes in purchasing raw material (raw fish, ore, coal, bars) since many people want to Buy RS gold to quickly level up their skills (they know that they will lose money but gain quickly skills XP). It is possible to market 100.6 million gp of mithril bars to buy a Santa Hat, but by selling mithril full places to the Grand Exchange to purchase a Santa Hat, you would have had 353.1 million gp of mithril bars to create 100.6 million gp of mithril total collections (a gigantic money-losing proposal ).
