DS took online lessons via Skype off and on for a few years from a company in Cusco, Peru. We would prepay for 10 lessons or so and then schedule the lessons when he had time. Sometimes he would do 4 in a week, during soccer season he might only do one a month. They were very flexible and the rates were a bit less than $15 an hour depending on the size of the package.
DS has attended a boarding school this past year so he stopped the online courses at the end of last summer. We received an email from them today asking us if we were interested in lessons again as they apparently are getting hit pretty hard economically from the virus. They have dropped the rates a bit too. DS said he would be happy to take the lessons again to keep his skills so we signed up for 10 lessons.
I know there have been many of us whose kids plans are up in the air given ongoing shutdowns and cancelled projects, etc. If you are looking for additional activities for your kids, for the money this is tough to beat and I think they could use the work.
Please PM me if you need any more info or specifics. They can be found online as Proyecto Peru Centre.
