Need to improve my track

I need help with my track which is I believe 90% done. I’m fairly new to producing but I want to get the most out of this track. Bringing this track to the next level would mean a lot to me. It would be great if I can get your help to further develop my skills and knowledge. There is no real deadline but the sooner the better. Looking forward to hear back from you. Thanks, Sascha

Additional info:
I need the mixer to do some editing, time aligning and vocal tuning before mixing. The song is fully recorded. I just need mixing and mastering.. I'm interested in working with a very experienced mixer. I'll need you to master it too if possible. I don't have a hard deadline for this. . I represent an artist.
