Need 1 song Mixed and Mastered

Hi! I need to get a project mixed and mastered. The project isn´t fully complete yet, but will soon. It is about 50 single tracks, but about 12-13 stems. The song is some similar to Hardwell, Tungevaag and Zedd (EDM). The Vocal is in norwegian, not in English. Does this get it difficult to accomplish a good result? And how much do you take? Sondre
