Making money with Dirge

These days my interest with raiding seems to be diminishing due to various dramas and my biggest goals seem to be leveling alts for money. A wise investment seems to be starting the Scepter of the Shifting Sands quest chain. This is a very long quest chain, which at one point offers an Epic cooking recipe (the only one in the game). It's very likely that this chain and recipe will no longer be available once the pre-Cataclysm patch hits live realms. Currently on my server this recipe sells for anything between 3-8000 gold and it's very rare to see it. With Cataclysm inflation taken into account, and the chances of this recipe being removed from the game, I can really see it hitting 20,000g. Even if the chain is not removed, the value should remain high. Now I have three characters who could still get this recipe (my main is a Realm First Chef, with every recipe learned, including this one), and potentially 12 others who could after leveling them to 60. The real trouble is you need a load of Brood of Nozdormu rep (neutral) to be able to progress the quest chain, which is probably a few weeks of AQ40 grinding, so doing this on more than two charcters is very tedious for me. I will most likely attempt to get the recipe on my 80 Shammy and 71 Druid, and forget the rest. I would reccomend people attempting this on all your charcters, because for four hours work the pay off is very good, whether you sell the recipe now or hold on to it for later.
