Need a chemistry tutor for high school level in Ireland

I'm looking for a patient chemistry tutor to help my teenager with high school chemistry. We need weekly sessions focusing on balancing equations, stoichiometry, acids and bases, and reaction types. Preference for someone who can explain concepts clearly and provide practice problems with solutions. Flexible on format—in-person near [city], or online if schedules align. Ideally available 2 hours per week across two 1-hour sessions, with occasional extra help before exams. Must have good references and previous tutoring experience in chemistry.
