Anybody wants to join in a choir as hobby? (Bangkok)

Hello, I am Eunji.
I am an opera singer who have sung for 10 years.
I would love to share joy of singing with people and make a choir in Bangkok.
Wonder how many people are willing to join in the choir.
My plan is to start it with 4 people minimum(Practice is going to be once a week). And if more than 20 people want to join, I plan to have a concert once a year.
Is there anybody wants to join? Please let me know.
Thank you.

Eunji
