Need help to find a job in Berlin

Dear all,

My name is Armine, I come from Armenia, Yerevan, now I live ion Yerevan. This year I intend to travel to Germany, Berlin, there I have a temporary accomodation to stay for two monts maximum, but I need to find a job in Berlin. I am an English specialist, and English teacher and I know German very well, from the first time I can accept any job that will enable me to get a working permit. So my question is: could you help me to find a job there? This is maybe much, but maybe you know some places where people are looking for employees. Im even ready to work in a reception.. in a customer service position.And what is the minimum salary for one person to take care about himself and rent a flat?

Will be thankful for your help and advice
