Looking For An Art/Drawing Tutor In Lincoln.

family looking for a part-time tutor, once or twice a week, for art, especially drawing. Our son is 12 years old and has become very interested in drawing and wants to learn more--ideally during the week in the afternoons. Someone with ability to later teach in other areas such as English/Reading/Writing is a plus as if a good relationship is formed we may want to expand to other subjects. We have a big friendly dog so must be OK with that. Thanks!
