For some of the Drupal-shops, including the one I work at, community involvement is highly rated. Contribute to the larger modules, Views/Panels, or Core itself. Get some CTR-rating. (certifiedtorock.com). The number may look meaningless, but people look it up when they are introduced to a new "Drupal-person". You can ping 'letharion', me on IRC if you wanna get involved in the community.
DrupalCon sounds like an excellent place to go, people are often recruiting at them.
If it gives you more hope, my employer, NodeOne, has a large percentage of people with similar backgrounds as your, including myself.
That said, CmdrPony makes a good point. Why not do something of your own?
