Network, network, network
The key to moving up in any field is networking. Develop contacts and friendships with other professionals in your area. You can do this at trade shows, user groups, and even vendor events. Keep this in mind: the majority of jobs people find are through the "informal job market" and are found through references, professional contacts, and personal relationships.
Also, when you are in the situation like your current situation, keep your eyes open for new opportunities both in and out of thecompany. I mention within the company because you should also look to build upon the situation you currently have. Do good work and make a name for yourself.
