Looking for a tennis coach for my kid (only in August)

We will visit Honolulu from Tokyo, and stay Aston Waikiki Vanyan between July 30 and August 25.  We are looking for a part-time tennis coach (student is welcome) for me (beginner) and my son (8 years old). Favorably, 2 hours, twice a week.  The date and time are flexible for us. If you are interested in this, please let me know when you are avairalbe during the above period, and how much tuituion (per hour) you would like to be paid at issamartha@marble.ocn.ne.jp . The place where we stay has tennis courts, so the person who can come Aston Waikiki Vanyan is desired.
