I think the Web has hundreds of sites to that end, hence my qualms to post something like that. Anyway I will make an exception, notice that
There are other teacher advertisements there to be seen. Anyway, there are lots to see, perhaps even back in your neighbourhood.https://www.superprof.com.br/professora-ingles-portugues-ajudo-corrigir-trabalho-conclusao-curso.html
I took an English course some time ago and the teachers were more than happy to do some teaching on the side, it would give them some extra bucks.
I hope you find a good one, English language should be taken seriously by both - learners and teachers.
In time: I am not in anyone´s payroll, so it was a site taken at random.
