Hi. I'm a professional music producer. I used to normally mix and master for free on reddit but I decided to sell my services.
Experience:
I have participated in r/RandomKindness before to offer my services to people for free. I mixed and mastered 3 people's songs (privately) and made 9 slowed+reverb songs with my mixing plugins. I also have a lot of vaporwave songs under my catalog which are on my soundcloud (linked below).
Mixing+Mastering will cost you $60-150 per beat depending on the size and duration of the song. Pricing can be discussed.
Other remix type services can be discussed privately if you want that.
If you need assistance on how to get your song released on music services such as Spotify, I can help you after we're done with the song. It's completely free of charge.
Process:
Because of DAW barriers, you will send me stems and I will mix and master in my own DAW. I will take full instructions from you on how you'd like the song to be done. I will try to be as less of a barrier between you and your creativity. If you need ideas, I'll suggest but you'd be in FULL control of the project. YOU will instruct me on how you would like the song to sound. If you don't like the results, you will be refunded. But it has to be a valid reason and you have to specify what you don't like about it. No vague answer such as "i dont like how this sounds". Valid answers are "i don't like how this instrument is dominating over this", "I don't like how the snare sounds too loud", and etc. Reminder that all of those can be fixed.
