I’ve been using iTalki and it’s been working really well. You can do a couple of half hour taster lessons to help you settle on a tutor. Costs depend on the teacher and varies from around $10/hr to $40/hr. the cheaper tutor are more about conversation but there are a number of professional teachers there as well. I try to do a conversation session once a week, typically at the lower end of the cost scale.
I also found a local tutor and we meet once a week. This is a lot more structure around building grammar and comprehension. It’s $40 a time but it’s really working.
