If you are in the SF Bay area, you might check out Chabot College in Hayward. I used to know an employee there in the CIS department and was told that they were looking for an instructor that could teach a web programming course. They were looking for an instructor experienced in Perl, CGI, and SQL (MySQL or Oracle) on Unix.

I don't have any contact info but the department is small enough such that you can probably talk to the head guy directly buy getting the number from their web site.
