We've not had very good luck with Craig's List when it comes to professional, skilled personnel. There are several more sophisticated employment sites out there, at varying costs to use, such as Monster.com. But before using them, I'd look into what the California Society of CPAs has available. They might offer a jobs listing board at their website or in their publications, and then your listing will be going straight to the source. You'll be hitting only people who are CPAs, or are in the process of becoming CPAs. Don't know about California, but many state CPA societies do have such boards.
