I dont find getting the gold as hard as not using them. so if you dont use gold on professions or buying items/potions/ect from ah. you shouldnt have any problems getting gold for your mounts.

i would farm SM. A full cath run are good xp and 10-20 gold plus i remember selling the blue boe item that dropped in sm for 10-15 gold each on ah.

On my server disenchant, mining, herb and skinning are a nice way for some really easy gold.
