Need a chemistry tutor for high school level lessons

I'm looking for a patient chemistry tutor to help my teenager with high school Chemistry. The sessions should cover core topics like atomic structure, bonding, stoichiometry, and basic organic chemistry, with a focus on problem-solving and exam preparation. We prefer 1-on-1 online lessons, 2–3 times per week, 60 minutes each. Please tailor lessons to the UK curriculum, be ready to provide practice worksheets, set short assignments, and track progress. Flexible schedule, but aim to start in the evenings after school hours. Prior tutoring experience and familiarity with GCSE/A-Level standards would be ideal.
