Hi "JJ's"
If the two of you are still considering native English-speaking teachers, you can email me with some idea of what you want help with via:

My students are mostly secondary schoolers, a few uni undergrads and working adults; and I'm especially looking to increase my tutoring experience of this latter group - now that we're at the brink of summer break (which is never quite LONG enough, with SO much to do
).
By the way, I'm female, British-born Chinese, and have been in HK several years, initially English language editing then teaching (while studying, too).
Anyway, wish you luck on your search
