Life / Cost of living in Gdansk [16]

Hi,
I am about to qualify as a teacher of English as a foreign language (CELTA for those in the know). I am also an experienced computer programmer (10 years)

So, moving to Gdansk in late September and trying to work out if I can earn enough from teaching to live in Gdansk. I also have to pay for my car back in England which is on credit. Unfortunately, getting rid of the car is not possible or I will still be paying off the credit and simply have no car!

I understand my cost of living may be something like this each month

Flat 1300
Bills 300
Car 1000
Food 1000 (for 2 people)

Does this sound about right for the area? Is there anything I missed? Could bills be more?
of course, this means I need to earn at least 4000zl net to just survive to a basic level. Anybody know the TEFL industry know if this is even possible for a newly qualified teacher?

Many thanks in advance and maybe I'll be on this forum a lot over the coming years.

Tony
