Need help producing a 12-13 song record

I am going for a heavier grunge type of sound. I recorded all the guitars as DI tracks that need to be re-amped. I would like the sound to be like a heavier Nirvana type sound but also a littler experimental if that makes any sense.

Additional info:
The tracks are cleaned, tuned, and and the song is ready to be mixed. I'm an indie artist. I'll need you to master it too if possible. I need it by 24 September, 2023. Check out the song I attached. The song is fully recorded. I just need mixing and mastering.. I'm interested in working with a very experienced mixer.
