Where do I begin searching for a day cook? (Not live in)

My mother and I are chronically ill, so it's become quite stressful to keep up with cooking, meal planning etc We need someone who can make healthy meals and is flexible for suggestions. Like maybe someone who can come cook for a few hours in the morning and leave. But I'm open to any and all suggestions for our issue. The most important is needing someone trustworthy because the primary need for this service is our health.
