Here's a list of some http://mynge.com/music-forum/music-industry/studio-listing/tennessee-reocording-studios/356.html

I only have good experiences with using demostudios in Nashville, they are nothing but excellent for publisher demos, and the rates can't be beat.

I aim to produce full band demos in my homestudio, and learn a lot from getting pro demos from Nashville of my best songs. I can never beat a Nashville studio, and I'll always have to use outhouse vocalists - but in all modesty I hope to develop a voice as a producer, that can work for some of my output, at least once in a while. Also to be able to pitch my own stuff for tv/film, without paying expensive master rates. All of this is really helping me to develop as a musician, engineer and producer, as well as a songwriter.

Paying a pro studio is really just the tip of the iceberg, as - finishing up my songs, doing the research on possible pitches and reference songs, record a proper worktape, communicating with arrangers and session leaders, listening to how the musicians choice of voicings, signature licks and bag of sound tricks really support every line, and the perfect mixes - all of that is invaluable as a learning experience. Now, I just hope one day to be able to be present to some of the Nashville sessions too.

So instate, inhouse, outstate, outhouse ect.. well, you can choose to be a house musician or local politician of course, and thats quite honourable in itself, but if your goals are getting cuts in the pro game, you'd be better off to do what ever it takes, and get an attitude that works to support that.

That's the required business way.
