Companion Care Needed For My Father

About who needs care: poor memory. sometimes forgets to take meds. forgotten things on stove a couple times in the last few years. left the garage door open and forgot about it once. main thing we are looking for is someone that comes in after lunch and makes sure the stove is turned off. he makes his own food, but it would be helpful if someone helped him prep food. my wife and I get home around 4:30. looking for possibly a 12:30 - 4:30 time frame M - F. Cantonese or Spanish would be ideal, but he speaks English (his hearing is not good, and Cantonese / Spanish are much easier for him) About the care needs: He's quiet, so someone that can just be present and ok with quiet would be great. And someone willing to answer the same question multiple times. Services needed include: meal preparation, errands / shopping, light housekeeping, and companionship.
