Hello and hope you'll like your new direction! :-)
I myself was originally a music producer, mainly in industrial, synth pop, different kinds of rock/metal/goth, and ethno. The transition to sound editor was not painless, the approach to sound in music is very different from that in film, but for me the very naturalistic ethno (mostly African, Latin American and Indian) gave me a good understanding of keeping diegesis (making it sound genuine and true), and the sometimes extremely complex industrial/noise-music trained me in layering and maintaining order in chaos. The next step, developing into sounddesigner, was easier, as I already by then knew how these things worked. Though I do have a diploma as a professional sound engineer, mastering technician, and producer, I had to learn everything about film for myself.
I started out by joining a casting-site for the full business, and for years I jumped on every amateur project I could get, till I finally felt I knew what I was doing. Of course some kind of school would've been a tremendous shortcut, but frankly, Swedish film-schools doesn't have a history of taking sound very seriously... Now I work both as a "one-man-army", as an employee of others, and sometimes as a supervisor.
What I say now is my own opinion when I hire people to work with, and it might very well differ from others opinions. For me, getting served a reworked clip from a movie makes me immediately compare it with the original. I don't want to, but I do. It also gives me a nagging worry that the person in mention is not used to working in collaboration with others, and when I hire additional crew I must know for sure I can trust the ones I coordinate to be able to think beyond their own very task, or I will be the one getting all the crap.
If I instead gets an amateur movie that might perhaps not exactly look like the matrix, but with a well balanced and interesting sound, I tend to take it for what it is and can see through the imperfections, focusing on the very thing I'm looking for people for.
