Answered Money Troubles...

2.2M at your level is actually really good. :o
As for gaining more cash, unless you are good at flipping/merchanting, it looks like gathering skills are they way to go. You should raise your woodcutting (yews/magics), fishing (lobsters, swordfish, monkfish) or mining (coal, iron). Skilling isn't the best money anymore, but it can still give some decent cash. When you get to a high combat level boss hunting is the way to go. I would also suggest using kingdom management, that is lots of profit with very little effort.
You can also take a look at this: http://forums.zybez.net/topic/1421537-ho...5-minutes/ It does have requirements which you don't meet yet, but they are not too hard to get to.
