Advertising Tutoring Services in Taiwan

I was interested in teaching English and Spanish privately for a couple of hours each week, but I haven’t been very successful with advertising efforts here.

Tealit has some administrative issues, and a search of this forum indicates that they’ve worsened with age.

I checked the PTT and helped some people with their English and Spanish questions, but I didn’t find any freelancing boards there yet.

Where are the places to post simple ads for private instruction?
