Native English teacher (Dubai)

Hi :)
Have been teaching for nearly 10 years in a bunch of countries. Am presently teaching full time here in a school. But would like to work fewer hours. Does anyone know of a family who are looking for a part time teacher? or a school? I have my residency but if I left my current job I guess I would have to get a new sponsor. Is this possible if I only work part time? Need to work less and get a life!
Any help/suggestions would be appreciated.
