Optimize production of my Piano/Electro track "End of Time"

Hello I am JulienB, French Pianist & Composer, I have self produced my electro/piano track "End of Time" for my first album, I received feedbacks from music industry professionals. Positive aspects are nice melodies, well structured production however I am looking for a producer to help me to optimize it and improve especially the following elements: - Optimize the drums and beats - Optimize the bass and the overall groove of the track (sound design, groove enhancement...) - Add some potential layers to deepen the track if relevant (especially during the breaks) - Check the structure and let me know if I can still improve some aspects to get to a real professional level I am really looking for getting a full professional track at the end. When optimized, I will then ask a singer to add his/her voice on the track and finally ask for the final mixing and mastering but that will be part of the next steps/projects. I attach you the current .MP3 Mastered track. Thanks in advance for your support, Regards

Additional info:
Check out the song I attached. The song has somewhere between 10 and 30 tracks recorded that need mixing. I don't need the song mastered. I need the mixer to do some editing, time aligning and vocal tuning before mixing. I'm looking to hire a top pro who's worked on hit songs, and have the budget for that. I need it by 23 May, 2020.
