I tried a few after my wife received a ticket and didn't get a single response. Ended up just finding a lawyer near the courthouse on Google Maps that dealt with traffic tickets, and have been very happy with his performance thus far.
Spend a bit of time as an *observer* in the traffic court/the judge(s) you expect to appear before. Defendants with attorneys have their cases called first. Gives you a chance to see different lawyers in action and *compare and contrast* Ask for the business cards of any who impress you. Stick around afterwards and see how the court handles pro se defendants as well. You'll get to see what works/what doesn't.
My buddy got a ticket after a minor fender bender. I used one of those lawyer-locator web sites and got referred from one attorney to another to another. Finally just picked a local, in-town attorney who got the job done.
