Has anyone hired a babysitter for spontaneous L&D?

I'm due in June and am 5 hours away from the closest relative. I'm thinking about maybe hiring some help should I go into labour before my mum gets here from America as she will be arriving quite close to my due date. Has anyone done this before? Where do I even begin to be able to find someone that would be willing to be on call like that? Any advice would be appreciated
