I wish I could help you but the best I can come up with is finding some that work with larger companies that support telecommuting. Most of the smaller companies that support remote work generally use networking, ads or independent recruiters. Telecommuter jobs collects the Craigslist ads that mention telecommuting but the results are spotty. Dice.com might have a better search but I cannot recall if they have a telecommuting filter; if they do you could look for recruiters that post there.
