Looking for nice helper

We are a family of 5 with working parents, 3 kids of 13y girl, 12y boy and 1y girl toddler. Grandparents visit every day to handle toddler cooking and caring. We need a helper to do household chores eg marketing, buying groceries, laundry and cleaning. Assist grand parents on taking care of toddler if needed. Grand mom does marketing and cooking as well. Helper’s role is mainly to assist and co work with grand mom on cooking and marketing. Helper will sleep in a small separate room. We are looking for a helper who is hard working, willing to learn and obey instruction, patient and good temper. Our current helper is going to end her contract by end of February. Expected new helper to be on board on 1 March.
