Temporary Care Needed For Parents While Visiting DC

My parents will be visiting from April 3-9 and I am looking for a caregiver to help them during the day while they're here (10-12 hours/day except for their final day where they fly home). My mom has Alzheimer's and is mobile but a bit frail, and my dad has significant foot pain which leads to some balance and mobility issues. The help would mostly be for my mom; she needs at least some help with dressing, bathing, toileting (especially with public restrooms), taking her medication, and sometimes eating. My dad might also need some help with balance and fetching things, but much less so than my mom. They'll be staying at a hotel in DC for the week.
