Well... That's a good question. I'm not paid for doing anything, it's just a hobby of mine. I've got a full time job, and I'm working on a Master's degree. I also get burnt out pretty easily, because RPGMaker crashes all the time and deletes my progress.
So, quite some time, I'm afraid to say. If I had more time or I was a harder worker, I could probably hurry it along, but as it is I can't promise anything.
That said, I'm uploading my current progress right now, so there's at least something available for you to play.
