Need overnight care for 104 year old female

Our mother is 104 years old. She ambulates with a walker, but is getting weaker and at further risk for falling at nighttime when she is alone. Looking for caring, experienced caregiver to be with her from 8pm-7:30am M-F to assist mostly with ambulating and toileting during this time of the night. She is hard of hearing, has dementia, but the sweetest person you could ever hope to know. Cantonese speaker a plus. Must have car or reliable transportation to and from. $20/hour. If interested, please send resume or list of experience. Thank you!
