Are you sure teaching English is for you?
Bear one thing in mind - Polish employers are ruthless. If you mess up too much for their liking, they'll cut the work from you without blinking an eyelid - especially in Krakow where they can replace a native without any effort whatsoever. You can also expect students to be demanding - after all, it's their money.
You'd be best to try and get a job in a Callan school - but - they're going to pay absolutely peanuts. 30zl an hour, with no holiday pay or health insurance isn't going to go especially far in Poland if you've got a family to feed - especially combined with the ridiculously antisocial hours.
Now - if your girlfriend is earning good money by Polish standards (let's say - anything over 5000zl gross) - then it might work. But if she's working in a low earning job, you're going to find it a real struggle - no job security, in a competitive city full of people willing to offer "konwersacje" for beer money - it's really not a good bet if you want a future.
If you want to make it work in Poland, then my advice is to go to somewhere unfashionable. Rzeszow, Bialystok, Lodz et al.
