Narrow Runway,
I do not know where do you have 800Eur figgure from. The one I know is bigger than that, so no lower than 1200EUR for the first year.
And one CAN live on that in eastern EU. It is not much, but one years goes fast and do not forget that on top of that your Type Rating is being deducted. So your sallary is around 2000eur.
Considering todays situation in aviation this is, from my point of view good chance.
Kind regards
