750 gold total (The bonus is extra gold) after gaining at least 1000 for assassinating the bride during her speech. It's suposed to be unavoidable. I turned invisible and ran away, but I talked to the argonian and I instantly gained a bounty.
Time it right.... and you can shoot her, wait for everyone to move out of the way, jump down, steal her clothes(only wedding dress in the game I know of), jump down again, run to the tower with an entrance to the waterfront and escape with 0 bounty. You do have to avoid the argonian though.
All the bounties I've ever had paid 100 gold, regardless of what hold they're in.
Dragons are 500 gold, that is the one exception.
Working for the stormcloaks at level 60 I remember getting semi-decent(not what I wanted, but worth something when I sold it) enchanted stuff after every mission, then getting stormcloak officer gear(crappy but I get why they gave it to me)... then out of no where... a hide shield. The reward after that was a deadric sword of the vampire so I guess that makes up for it... but really, I fight a war for you and I get a hide shield? I'm wearing a full suit of enchanted deadric armor, I command the mages guild, I turn your enemies against each other with spells then summon deadra to help you in your battles... I'm WINNING you war for you and you think it is acceptable to give me a freaking HIDE shield?? I would of switched to the empire at that point if it let me.
