Professional Mastering Engineer Needed for Personal Ambient EP

I'm looking for an experienced audio mastering engineer to professionally master an 8-song ambient/instrumental EP. This is a very personal project to me, and the music is essentially finished. I produced the tracks myself and have already done the mixing and initial mastering. I'm looking for someone with a professional ear to take the finished mixes and give them a proper final mastering pass for release. What I need: I need mastering only. I'm specifically looking for someone who can: Professionally balance the overall frequency spectrum Optimize loudness while preserving the dynamics and atmosphere Control peaks and transients appropriately Check for clipping, distortion, unwanted resonance, phase/stereo issues, etc. Make sure the tracks translate well across headphones, speakers, cars, phones, and other playback systems Create consistency in loudness and tonal balance across the entire EP Make sure the beginning and ending of each track are clean Make sure fades and silence are handled properly Deliver final, high-quality WAV masters suitable for digital distribution Important: I DO NOT need production or mixing The creative production is already finished. Please do not add: Reverb Delay Chorus New instruments Synths Samples Sound design Creative effects Arrangement changes Melody/harmony changes I'm not looking for someone to "make the songs bigger" by adding effects. I want the existing sound and atmosphere preserved. This is ambient music (the last song is hip-hop), so dynamics, space, warmth, and atmosphere are important to me. I don't want an overly compressed or aggressively loud master just for the sake of loudness. If any individual elements, frequencies, or sections feel noticeably too loud, harsh, boomy, muddy, or unbalanced, I also want those issues addressed during the mastering process where possible. The goal is to have the finished tracks feel balanced and cohesive without changing the character of the original production. About the project The EP is called From The Mind Of O.A.: The Origin Awakening. It's a conceptual ambient project dealing with themes of life, identity, growth, time, mortality, and awakening. The music is intentionally atmospheric and reflective. I want the final masters to preserve that feeling rather than turning the project into something overly loud or polished to the point that it loses its character. I have already done an initial mastering pass myself, including loudness adjustments and peak/clipping checks. I'm looking for someone experienced to evaluate the work professionally and improve it where necessary. Deliverables 8 final mastered WAV files Consistent mastering across the EP Streaming/distribution-ready masters Revisions until we get it right. I can provide the original high-quality WAV files and any relevant notes about the intended sound. Budget $200 fixed price for the complete 8-song EP. Please only apply if you're comfortable working within this budget. When applying, please include: A brief description of your mastering experience. A link to your portfolio or previous work. What you would specifically look for when mastering an ambient EP like this. Confirm that you understand this is mastering only and that I am not looking for additional effects, production, or mixing. I'm much more interested in quality, experience, and someone who understands the character of ambient music than someone who simply makes the tracks louder. If you've mastered atmospheric or conceptual instrumental projects before, I'd love to hear your work.
