Pro Mastering Services Wanted--looking for a long term partner

Hello, Long time musician (45 years) and self producer / engineer / mixer (25+ years) here. I have a nicely equipped home studio where I make music.

Looking for a mastering engineer to become a long term service partner.

About me: Mostly I produce experimental rock/alternative, with drums, bass, guitars, synths. I'm always looking for singers to collaborate with (I'm neither a great singer nor a great lyricist).

I have recorded in pro studios multiple times in my younger years (first album was actually on tape lol), have collaborated and been in bands for many years, tons and tons of live shows and touring in my younger days, and am very familiar with recording and live sound, so I am not a noob.

Also I do about 15% of my time in symphonic compositions.

What I am looking for: Mastering engineer who is experienced, reliable, good at communicating, and who will consistently turn things around in a reasonable amount of time. In other words, a professional. Hopefully one who sees a long term relationship and will provide pricing that is relationship-friendly. Someone unafraid to critique my mix so I give them my best possible product to work on.

Having connections (think singers who are looking to collaborate) is a plus but that would just be a bonus, not an "official" ask.

If you are interested, I would hope to hear some songs from your portfolio as a first step. If you have references that you want to share, also a good step.

Perhaps as important as the quality of your work is HOW you work with others. I'm not wanting to pay someone who is difficult, disrespectful, or avoidant.

Thank you, and I hope to hear from you.
