I'm a senior software developer in Australia who have spent the last 4 months searching for talent at the junior level. I believe that experience is less important than attitude; particularly enthusiasm and initiative. If you have both--and it sounds to me like you do--and are smart enough, we can teach you the rest.
Please do me a favor and send your resume to me: sebastian@e-channel.com.au--make sure to reference this HN thread. While my team is currently full due to recent hires, we're growing rapidly and could be in a position to put on another full or part-time developer soon.
And even if I can't give you a job, I can hook you up with other budding entrepreneurs to collaborate with on projects. I might be available to give you a hand myself.
You'll get there. I've seen quite a few of your peers lately, and you seem to be way ahead of most of them in the areas that matter (at least to me). Trust in yourself and your drive will take you where you want to go.
