How do small books like 5Dimes and Legends get their lines?

[Thurgood]

I know this is a noob question but just wondering how different the lines are from Vegas. Do they outsource to companies like Cantor Gaming? Do they use their own in-house team? Or this is silly but do they have people in Vegas call the lines in?

most books plagarize sometimes they make a typo that is not too far off and you get good lines.
