Manburger Surgical LP

I have about 4 songs, shortest is about 10 min and longest is probably 17 min. The songs have many different sections and we didn't play to a click, just recorded live. There are some added layers of synth on every track. Looking for a producer who's into the music and has some good ideas for how to thicken the sound a bit. I tried mixing and am apparently not very good; sounds flat to me. I attached a sample mp3.

I'd like to have the job done by
