Babysitter Needed for my Children - Now Hiring

We have a wedding ceremony from 3 p.m. to 6 p.m. My Fiance has a 7-year-old brother (close to 8) who has a lot of energy sometimes and he's unpredictable at moments because he likes attention. We're hoping to hire someone who will take him somewhere nearby, make sure he doesn't get dirty in his suitr, and just kind of distract him and hang out with him for a couple of hours while we get the ceremony portion of the wedding done and then bring him back around 6
