Brief background: I started out as a producer and always wondered how to make my track sound equally cool next to world-famous artists. I went through a long journey to find the answer and quietly realized that I genuinely enjoyed the process.
I know that you have invested a lot of labor and time in the recording and production of your track, it is important for you that the mixing and mastering stage reveals the full potential of the composition and turns it into a really cool sounding song. It is important for you that the engineer understands you and your idea in music, guides your track through this process easily and without a hitch in the mode of convenient and fast communication, listens to your wishes and helps you find the best references to work on the song. 
So if you want your song to have the same vibe and polish as those currently on the top of the playlists, want your mix to compete with the big artists, I would love to create that sound for your track.
