Looking for domestic helper for elder care

We are looking for an experienced domestic helper to care for our mother who is 86 years old and lives by herself. She is healthy and very mobile. The ideal candidate must be able to communicate with our mother in Cantonese. Being able to read and write in English to communicate with us is a plus. The flat is spacious and the live-in helper will have her own comfortable room. There is wifi access. Pictures can be provided upon request.
