Seeing the overwhelming amount of acceptance in the other comments is amazing. But I do need to play advocate of the devil for a second here, and mention moderation.
I assume this concent will not be in English.
But if the existing moderators do not speak the language of the content, then they cannot effectively moderate. This makes it a massive risk to allow non-english content on your instance with only English speaking moderators. Hence, I would only recommend posting such concent to instances that are natively speaking the language. For example, German and Dutch content almost exclusively exists on German and Dutch instances respectively.



I can’t speak for the countries you mention, but I can give you an insight for The Netherlands.
First of, there is a big demand for English teachers in highschool (students aged around 12 to 18).
But. To become a teacher you need a university degree. Either a bachalors degree or a masters degree (masters unlocking the later ages/classes). See the following page for details: https://www.rijksoverheid.nl/onderwerpen/werken-in-het-onderwijs/vraag-en-antwoord/welke-onderwijsbevoegdheden-zijn-er
Also note that being a teacher is a tough job. Budget cuts have put a lot of strain on the sector, and the teachers do feel that. A lot of people burn out. However, the pay is decent, so if you love the job, you can thrive.
I mention all this, because I suspect that it is similar in other European countries. Hence, to get a good job will require proper preparation and some dedication. Maybe studying abroad in the country you want to move to first.
