Looking for a 24 x 7 Help (preferable female) in Noida Sector 78

Hello, My wife & I live in Noida Sector 78, and we both work. We need a full time help who can cook and can do the dusting around the house. We have a separate part time person for utensil cleaning & Jhaadu, Poocha etc. We have tried all kinds of agents & services available. Nothing seems to be working out. If anyone has any reliable leads, would really appreciate it.
