Being 1 defence it tricky with hunter. Graahks and Larupia ( I think they're called, the white snow ones) are very good money making methods giving over 800k profit an hour. But the graahks hit you so you wouldn't be able to do them... I'm not 100% sure really... It depends on what you like doing the most, both have their profitable ways.
Runecrafting for the past year or so has been rather dead for money making as runes have dropped so much. But I think you can get over 500k profit an hour from Runecrafting being level 91 I'm pretty sure...
I've linked some videos below you may want to look at. They're from YouTube and they're guides for money making with hunter and money making with Runecrafting
Prices may be out-dates as they fluctuate a lot, but hopefully gives you some useful information. Also it depends if you're botting or doing it by hand?
