Jobslinger.com is a free sign up that allows you to put in your zip code and search by radius from your zip. It can show some companies that have advertised shops recently that you may want to sign up with. Mostly the jobs will be with companies using the SASSIE reporting system, though Jobslinger also pulls posts from the Volition.com website and the MSPA website. Though the jobs you see posted are likely to be taken already, it will at least let you know what companies to sign up with.
