English teachers for online education

We are a non-profit organization teaching spoken English to more than 10 schools in rural areas in India. We are looking for teachers to conduct online classes on an hourly basis. Pay will depend on the proficiency and skill level of the teacher. All classes have to be conducted online and no visit to the school location will be required. Previous experience in working with non-profits is preferred. Also knowledge of any Indian language is preferred but not a must.
