I have good ears (I think). I have a working knowledge of current mastering software. I've done it before for folks who already have a mixed final product with great success. Do I need a piece of paper as proof? Is there such a thing as an apprenticeship anymore? What do you all think? I need to quit my current job in the worst way. I sort of closed my eyes and tried to think about what I'd be really happy doing, and mastering peoples music correctly came up as one of the top choices. Seems like a really hard fields to break into though.
