Companion Care Needed

We need companion care to take care of my adult child in Richardson. We're looking for someone to provide companionship. Preferences for a caregiver who is a non-smoker. I will be attending a conference from the Sep 16th at noon through the 19th at 3 p.m. Schedule is roughly as follows: Sep 16: noon-10 p.m. Sep 17: 7am-10 p.m. Sep 18: 7am-10 p.m. Sep 19: 7am-3 p.m. I will be in the hotel in the conference area, so I will be available if needed. I am also open to split schedule. I'm just trying to find out if anyone is available and if so how much. Thank you, Christine
