Music Mastering

I need an audio expert or engineer to "master" an Ableton project. I have very little experience with Ableton , therefore some tracks use unconvetional methods to archieve the "sound effect" that we want, specifically several filters and effects which one would not normally use for sound design. Just because I do not know how to create the effects/sounds i want with synths. Those all i think be left as they are. However it needs fixing dynamics and equalizing of the tracks in general, so the song would sound 'complete and professional'. The purpose of the track is that it is supposed to be used as a background for a live vocal duet performance of the song on Thursday. I have included the voice tracks in the Ableton project, but they are just placeholders and turned off. The end result should be mastered without voice, with the voice tracks turned off. I need this ASAP because the performance is on Thursday. I will share the Ableton project/pack as a Dropbox/Google Drive folder whichever is more convenient.
