Night time sitter for 2 boys after a wedding in Meredith, NH

We are a family with two boys, 5 and 7 from Medfield, MA that will be in Meredith, NH for a wedding at the beginning of May. Looking for a babysitter at our hotel, will just be putting boys to bed, ensuring their safety. We will be in Meredith for my sister-in-laws wedding. The boys are in the wedding and will be going to the reception for the beginning. Looking for someone to put them to bed once they are ready to leave the reception (probably 8-9pm). Will have the sitter come to hotel around 8 so that they are around once the boys decide they are ready to leave.
