Seeking Flexible Part-time Senior Care Provider In Iowa Falls

I need senior care provider with experience. Our care concerns are: Meal Preparation, Companionship, Errands / Shopping. Seeking someone to handle meal preparation. Duties include providing companionship and social interaction. We'll need you to handle groceries or errands when appropriate. My mother is in the early stages of dementia. Her short term memory is very limited. We just want her to be safe when my dad is gone. He drives/ moves vehicles part time for a local car dealership and his schedule varies from week to week. Looking for someone who is flexible and can work with short notice. Thanks.
