Hello!
This is my first post, so i hope you like it.
Everyone knows the struggling with the gold for the mount, but this will make it LOTS easier.
In Desolace, at the Shadowprey Village (Coords: 24, 70), at the docks, a troll named Zinar'Zillen, will give you this quest: "Fish in a Bucket"

It is REPEATABLE, and oyu get 55silver for each time you turn it in.
It requires 5 min. of swimming, and finding fish cases. Those cases are big, and easy to find.
That's all, i hope you like it!
