Yes, work on the network. Inspired by a conference 'open session' on job hunting a few months back, I wrote a blog post explaining this with some more specifics which may be of help to the OP (or ideally anyone) at http://michaelkimsal.com/blog/working-your-network/

In a nutshell, spend time in small groups - explicit networking groups, or networks of friends/colleagues with similar but disparate interests. None of this will be 5 minute job, but the OP has already invested months cold-emailing for jobs and that hasn't worked. Spend time investing in keeping your own network connections going - meet up with people regularly, etc.

Perhaps more importantly - start your own group if you need to. People will end up finding you and reaching out to you with job offers because they want to access your network. You'll sometimes hear about gigs before they're available anywhere else (not often, but it happens).
