‘You get what you pay for’ is an old saying my mother used to tell us. Equally true is ‘You pay for what you get’. A qualified professional (and by ‘qualified’ I mean a native speaker who is a teacher with many, many hours’ experience and an expert in the language) will not let their skills go for such low pay. Would you go to a doctor that had the lowest rates in town? He probably also has the least experience and years of study. You just know from experience this is something to avoid.
