I wish there was a simpler answer, but a good way (which I've seen posted several times here) to get remote jobs is via referrals or word of mouth.
My first job was to build a simple website for small business a couple of years ago, and now I get calls for things like sharepoint deployments and ecommerce sites. At the moment I have more than I can handle and have to turn down gigs.
You've got to build a reputation with your first project and sell yourself hard.
Beyond applying via job boards, what else have you been doing so far? Please be specific, perhaps we can offer some job search suggestions you've overlooked.
