Help with cleaning up score for minus one recording

Hello,

I don't know if I am posting in the correct forum, but I am relatively new to MuseScore.

I have an approx 5-minute arrangement I have created with piano, oboe, bassoon, cello, and tubular bells on MuseScore. It is to be played as an accompaniment for my choir to perform live to as we cannot have live instruments play.

What I need is someone who can clean up the score so that the sound fonts and dynamics are decent and appropriate to accompanying a choir (with soloists). The file will be burnt on CD as an mp3 file and played through the PA system in the small venue.

Is there anyone who can help me with this? I have never done sound mixing in my life. I need this done urgently (in 24hrs). I am willing to pay for the services if they are indeed professional services that are being offered.

Many thanks
Rosenkranzio
