But really, aren't all non Buffyverse vampires usually ensouled and cursed with the thirst? I mean, Blade never really explained why Hannibal or Krista were the only vampires with a conscience? I mean, aside from frequent showers and the serum.
But frankly, the rules of the Buffyverse aren't that hard for vampires. Find a slaughter house, try not to get on anyone's bad side, et al. I mean, unless you find yourself in "The Church are the real bad guys" tm story, the only real challenge would be finding the money to keep WR&H on retainer to handle the paperwork. I mean, I assume they run an undead services department of some kind.
