I don't know anything about lawyers in Croatia. In the U S going to an attorney with a $3000 claim would get you laughed out of the office. They'd tell you to take it to small claims court.
Also (and I was told this some years ago by my own lawyer), if the lawyers think they have a criminal case they would pursue that FIRST. Then, when you have a guilty verdict, you go to civil court and use that as proof of responsibility and damages. It makes the civil trial a slam dunk.
