What kind of job will allow me to work at home while still caring for my aging parent?

I live with my parent and have been caregiving for a number of years. It appears that additional caregiving may be needed in the future. I wish to be able to provide in home caregiving and would like to find a work at home position which would enable me to do so. Does anyone know of legitimate work at home positions for a professional with a background in social work and volunteer mangement?
