Now I know why nobody replies to your emails. Sorry, but with that kind of attitude you are not going to score any interviews in Poland, with the current unemployment rate at 15%. Simple.
Dave, your English has spelling errors etc. You do need to work on it. Now let's talk about teaching English for a moment: assuming you wanted to, in the cities there are probably too many English native speakers already and the jobs are fewer. When I am out and about I am amazed at how many under 40 year olds speak pretty good English already, thanks to their school, uni or -- as one or two have told me -- just watching American movies and TV. I think the work for English teachers is falling away, so it's good that you want to do something else. If I could think of anything, I'd let you know. When I first came I tried approaching many firms, I only got one answer and that was just a thanks but no thanks. I can even recall one firm ignored me even with me offering to work for free on a one-week trial basis and at very much a reasonable rate thereafter! Hate to say it, but they just don't need us much or at all, unless we have a specialist skill such as economics or IT or engineering. If you have any of those, you should keep trying perhaps, and I hope you do well and understand that nobody here meant offence, they were just pointing out what you need to work on to progress. Of course, none of us are perfect ;o)
