Looking for a maid, to take care of an adult mother and a teenage boy only

Currently, we only pick up students after school at 4 PM for dinner and do not require home-based work; part-time is acceptable. There is a three-month probation period, and if qualified, long-term employment will be available for home living. The purchased house is still under construction, so we are temporarily renting. After the house is delivered, there will be a separate room and bathroom for the domestic helper.
