Thanks Pete,Hey Andrew!
Ideally, you should join a Huddle where we discuss this sort of thing quite regularly.
Tim is right, getting experience of the pub industry in the “traditional” way is an excellent way to (hopefully) work with good people and to learn how stuff gets done.
Many / most successful self-publishers (and why be any other sort of self-publisher?) get their start first in traditional publishing then leverage themselves to self-pub.
p.
Say I'm writing a trilogy...could one ditch a publisher after the first book and self-pub to second two...or does one get locked in? (All wishful thinking of course).
