I need 1 song mixed

I need 1 song mixed. I am basically done with the song, I would like to publish the song as an EP on iTunes, Spotify, Soundcloud, etc. which means I would need the track to be in its highest sounding quality. I would also like feedback on a bass line which I have not added yet and am having difficulty with. Feedback, and and high quality sounding track would be an amazing opportunity! Thanks so much.
