Professional Song Remaster with Bass

I’ve already recorded a complete track(not by me but another artist) ; now I need a skilled audio engineer to give it a polished, release-ready finish. The priority is a balanced, warm bass presence that compliments the mix without overpowering it... (Budget: $10 - $30 AUD, Jobs: Ableton, Audio Engineering, Audio Mastering, Audio Production, Audio Services, FL Studio, Music, Sound Design)
