Best gold farming method with DK?

I just leveld my Blood DK to 90 and want to try gold farming. I'll gear it with LFR and Timeless Isle for farming dungeons but I can't decide which Instance is the best to farm with 90 DK.

Can someone help me about it? People farming dungeons 8 - 12 hours a day and making 10k gold easily. Which dungeon is that? Or is Timeless Isle farm better at gold per hour atm?

Please help me to decide which way is better for me to start farming.

Edit: It can be private profile aswell, doesn't matter.

 

I'm not sure you realize what private means.

 

I meant private profiles which people sells. That is still private.

 

"People farming dungeons 8 - 12 hours a day and making 10k gold easily. Which dungeon is that?"

I'd love to know that too.

 

10k gold for 12 hours a day? that's awful

 

instead of trolling, just say how to make it better. even ~1k/h is difficult for most HB users cuz they do not have the know-how and the experience.
