Joanne Cooper (she's on this site under users) put together a 9 or 10 video series starting at step 1 basics and progressing to putting the song on an album. She charges a small fee, totally worth it. That's how I got started, although BIAB has so much more I don't even know about. But I can compose a song, pick a style, get the chords in, export it to a DAW, do the vocals or add myself playing or a lot of other things, save it as a wave file, export it to Audacity, so some further tweating and finally save it as an MP3. Send Joannne a private message on this site to see if she still has her online class available. If will definitely help you get started.
