One possibility you might consider (if the nature of your work permits) is hiring Perl programmers who work part time and/or remotely. I know that I have often been willing to take on side projects but am not willing to relocate or to do much more than occasional travel. Without exaggerating or trying to be snooty, you would have to offer me at least twice my current salary to persuade me to live in the bay area. It is possible that others feel the way I do.
