Aside from the "move immediately" advice, I'd suggest getting your code out there in a more public way. This dramatically increases your chances of being hired, because it replaces the technical interview. You just have to prove that you're capable of dealing with other human beings, and most people can do that.

Do something -- anything -- to get your code out there. Even if it's the most obscure and idiosyncratic library, throw it on Github.

I got a ticket to the Valley on the strength of some decently interesting (but by no means amazing) open source code. And I'm not even American and have no CS education, so it was considerably more difficult for me than it will be for you.

Incidentally, my current employer, the Wikimedia Foundation, is very open to remote contractors. (I caution you that we tend to be a bit slow to hire.) If you want to continue to live in Michigan, you won't be unique in your isolation, because these organizations are basically run over the internet. And your salary will go much further if you don't have to deal with rent in SF. http://wikimediafoundation.org/wiki/Jobs
