Need one song mastered / possibly re-mixed

Interested in testing the waters with mastering one song. It was self-recorded / self-mixed, so looking for honest feedback on raw track quality and can provide individual tracks for re-mixing / feedback on raw recording quality if moving forward and that makes sense. Original tune was done for a friend starting an Instagram sandwich/food review trend slowly gaining momentum. Interested in hearing about pricing.

Additional info:
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. I'm looking to master one song.
