you can do all that before even knowing what city this person lives in?
Yep, a network of respected colleagues on call over most of the country. Of course, if you want a class next to Lake Solina, the price might be a little higher...

If you phone up a big school like Berl!tz, then they'll probably charge you 1000zl/for an 8-hour "immersion" day, and then they'll give the teacher 3-400 hundred of that and pocket the rest.
If you're in Krakow, there are excellent Polish teachers and experienced natives who will sell you a better course for a lot less than any school will charge. Their hourly rate will be between 60-100zl, depending on how many hours you want in one go.
Anyone who charges less than 1zl per min or more than 2zl is taking advantage of you.
