Violin or piano teacher

I need either one music teacher who can teach Grade 6 violin and above and Grade 3 piano to my 2 children, or separate violin and piano teachers. The children follow the ABRSM syllabus, although if you have taught over syllabuses please do make contact. You will need to help them with daily practice of scales and pieces, for 5 - 10 hours a week. Further projects are planned if this first project goes well. Experience music teachers only please. Please also state your expected weekly salary.
