Need producer for 1 song

My folk/bluegrass band are ready to invest to get one of our songs professionally mixed. We have some rough recordings, but would likely need to start from scratch. Also looking to work with someone who can guide us and help make some decisions about overall arrangement, and a multi-instrumentalist who could add in some additional elements. Our timeline is before year end. Let me know if you are interested! Thanks, Rebecca

Additional info:
I need live instrumentation added. The part I'd like you to record is already written. The lyrics and vocal melody are already written. I don't have a hard deadline for this. I'm looking to hire a very experienced producer. I'd like you to also mix and master if possible. I will be recording vocals on my own.
