Tutor Job in Chapel Hill, North Carolina

I am looking for an instructor to provide German lessons for my three boys at our Chapel Hill home for 5 weeks in June and July. My preference is for a native German speaker. Lessons would be done individually or with two at once. My sons are 10, 12 and 14 years old and at roughly the language fluency of a 2nd, 3rd and 5th grade German child respectively. My oldest is completing German III in high school. My objective is to keep their interest in German, continue to build their written and spoken fluency, and prepare them to enter German academic instruction as it becomes available in their schooling.
