Mixing

Looking to get my first professional sounding mix. Been making music for years but not knowing how to mix is really killing the spirit of any music I make. Looking for a more polished final edit. No rush with time but I want to start sharing my music with others.

Additional info:
I have a song already recorded and want some additional production elements - sound effects, synths, samples, percussion, re-recorded instruments. I need the vocals tuned as well. I'll need you to master it too if possible. I'm hoping to find a good mixer that can work with my limited budget. I don't have a hard deadline for this. .
