Strictly from a monetary perspective, wouldn't I just be better off ignoring this since the lack of proper data won't allow the ticket to be traced back to me?
Next time you get pulled over and there's an FTA warrant, you'll be arrested and your car impounded. It'll cost you thousands to get out from under it.

Otherwise, can someone point me to a really cheap traffic ticket lawyer site
There's no such thing as a cheap traffic ticket lawyer, or any kind of lawyer.

Be prepared to shell out $1500 as a retainer to fight something you are probably guilty of anyway.
