Homeschool Spanish Academy (or other suggestions)

Disclaimer: my kids are not homeschooled, I just thought you all might have resources.

I’ve got a 10 year old and a 7 year old in a Spanish immersion school. The school is very very good at the immersion part through second grade, with teachers enforcing the use of Spanish in the classroom. But when the kids get older they don’t speak it as much because their social language with each other (there are other non-spanish classes in each grade) is still English.

My oldest is fluent but needs help building a non-academic vocabulary. My younger is getting there and needs to speak it more often.

I would like them to meet with a native Spanish speaker once per week (online is fine) to just talk, and build their skills.

A friend recommended the Homeschool Spanish Academy but I have tried to get them signed up for trial classes 4 times now and they are really unresponsive. Anyone have good experiences? I’m ok to keep trying, but I’m also looking for alternatives.
