You need a timeline...
I am in the same position now as you are about to begin. I started working on my album last April - and well - it's now December and getting closer to being done. I really thought I'd have it finished in a couple of months - but when you have your own studio - the only expense is time.
I'm sure if I would have gone to a commercial studio & paid for the time - I would have been done a long time ago...
Good Luck & Have Fun!
