I didn't know about those costs, 25000 euros? Are they insane? So you're telling me that if I'm on holiday in Poland and I get hit by a car, I have to pay that amount on the spot? I seriously doubt it.
Depends how your Spanish insurance works. You'll be treated in Poland, but the normal procedure here (with the EHIC) is to get you stabilised, then when you're awake and aware of what's going on, they will want insurance details or payment towards your care. A Polish citizen would be treated exactly the same way - no insurance, no treatment.
But as I said - if your insurance works on the principle of getting the bill and then being refunded, you need to expect surprises.
I never said it was going to be easy. I just believe in my skills and experience, and I'm serious about this. I'm not underqualified. About driving down the rates, I know, that sucks. I've been told about that problem by many teachers and I don't know how I'll be able to provide quality translations (in its due time) at a fair price.
In the teaching market, rates are more or less rock bottom for natives. It's actually more expensive now to hire a good Polish Spanish teacher than it is to get a native. There are so many men here who 'met a girl' and moved here to be with her - and they need money to live, so they're willing to teach for a minimal price.
As far as translation goes, there won't be much demand for Spanish-English translation here. Same probem as teaching - too many natives, too little work.
I know there are some Spaniards there (one of my friends is working as a programmer in Poznan and I met three or four in my last visit), I checked some teaching websites, adds and language schools, even at UAM there are Spanish teachers. I know all that, but honestly, I believe it's easier to "compete" against that than to compete against 10 times more people in a dead market as Spain right now.
Bear in mind that you're not only competing against them as people, but also about their expectations. There's plenty of Spanish dudes here willing to work for next to nothing - how can you compete against them? I've met Spanish guys even working in kitchens and such like for pathetic wages - there just isn't much work for those who can't do something in need (such as programming).
Out of interest, how old are you?
