Need a reliable babysitter for two children from 5 PM to midnight

My husband and I are looking for a sitter for our two children Henry (11) and Maggie (8) while we attend a concert at the SAP center, in San Jose, on Nov 8. We are not local so we will be staying at a local hotel. We would need a sitter in our hotel room from around 5 or 6pm to around 11:30 or midnight. Please reach out if you are interested and available.
