I'm signed up with Servicemagic. I live a bit out of the higher population areas so I only get about one lead a month. With just that much the cost is minimal. I figured I'd just try it for a year and see. I've so far gotten about 1 job for every 2 leads which isn't bad, considering a few of the callers just had a question. In a larger city where they send leads to lots of companies simultaneously it could be a crap-shoot.
