I am sorry but from what I know, 30k€/year is more than the average wage (net) in most European countries, for a full-time job, mind you. In many countries, like Italy or Spain, it's even more like just 20k€/year. To US citizens that is often surprising but you obviously can't discount the social safety net, universal health care and generally lower cost of living, better public transport etc. in many countries. In that case, 20k€ year can definitely be enough to live on (at least until you have kids).
So I fear it is unlikely that you will find a part-time job that pays that much in most of Europe... But again, correct me if I'm wrong.
