There are agencies who provide live in carers for the situation your Mother is in, they provide rotating care, i.e. one person stays a week then has a week off. If you drcide to employ direct yourself, you will need a team of two or three people in order to cover for any length of time to allow for holidays, sickness, training etc.
From personal experience I would suggest an agency, the right agency with caring staff can be a real support for your family.
