Hello, Hannah. If you're not aware of it, there is a "teachers community" here on italki that is for teachers only. Here are two links that you might find useful:

I posted two links to similar topics.

what worries me about your project is internet access if you are traveling around Europe. If you are settled down in one place, no worries. But if you move around it’s a serious problem. Europe means several (sometimes small) countries with different internet and phone providers. Roaming can be very expensive! So that’s a very serious issue.
