See who you get, then decide where you want to go. If you're just babysitting, doing something more like Appreciation might work. Or just do glorified karaoke with tracks.
If you want to be more serious, there are some good groups on Facebook that can help you. Texas Choir Directors is one.
I did choir for a year. It wasn't as bad as I expected. Thankfully they hired a real choir director the next year.
