Matt,
You might want to check out
www.recordingconnection.com it is a program that offers on the job training at a real studio. It follows a curriculum of text and tests but it's almost all in studio time. You have to interview at the studio as if it were a job interview and must be accepted. It supposedly takes around 10 months and is around $4,000. The thing is you do it in your spare time. You keep your job and do it on weekends and in the evening. I don't know how legit it is but I was looking, the same as you and came across this place. If you call they will send you some info. I personally didn't have 4 grand so I had to pass. It seems worth looking into!
