My opinion is that you're putting undue stress on yourself with the startup. Your number one problem is that your 9-5 ain't so good and you need either another job or another income stream. Startup income isn't going to happen over night, so I think your efforts are not worth it given you're already stretched with the 9-5. I would be spending time on looking for either another job or a remote gig so you can give the 9-5 the flick. Have you considered moving to Sydney or Melbourne? There are a lot of development jobs in these cities that pay well for people with experience. Don't worry about the start up, I think. It's like worrying about wining second division on the lottery. Only work on it if you find it cathartic. Find another job, move cities if you need to.
