The first may work, but I still think that most players wouldn't bother to do that. They can always search for the same loot in the Black Market and it'll certainly come out cheaper than an on-demand service.
The second just doesn't make sense in a game where you can respawn after being killed and keep playing again at little to no penalty whatsoever. Unless you live on China and think that hiring digital hitmen is a wise way to get your son/daughter out of the game.
I see. On that note, how would guilds/clans be organized? Is it strictly limited to teams? I'd like to know because I imagine there'd be some sort of mega-group that trains/hires/fights en masse, using scale to its advantage.
