Talk to my friend David Stamm. He might be able to help you. I was just talking with him earlier and remembered this thread and he told me to have you contact him.
You don't need a lawyer just go to the clerks office at the court house and file the paperwork yourself, there is a fee per "Item/charge" submitted for expungement. as long as it has been a year since the original court date you should be GTG, I spent like $350 total expunging my record a couple years ago.
