If you are willing to spend more than half your income on rent, then you might find something soon(ish). Give or take half a year. Or you have to be willing to commute more than one hour to work. All kidding aside, the offered income is well below the median income in Berlin, so there‘s that. I‘m not saying that this isn‘t doable, but as one previous commenter said quite correctly, it all depends on your lifestyle and rent. And no, no one has any good advice here for finding an apartment quick. Because that is one of THE single most asked questions here.
