What would be an ideal daytime job for a vampire hunter?

since the person is a vampire hunter he should have a job that doesn't involve a lot of other people and only works the day shift. i imagine him a pretty busy guy at nights because of his business and might want to look around for clues or battle strategies to beat the vampires so you should make him be a decommissioned soldier, but i think it would be more interesting if you make him a lazy part time worker it's your choice.
