You need to talk to a civil attorney that handles lawsuits against government agencies. It is very specialized so you may have to search for a while but keep trying. Also, you say you were convicted, so if you went to trial, you need to appeal immediately. If you pled then you will need to discuss the ramifications of a plea on a civil case. Good luck.
If you entered a plea of no contest or guilty to the DUI charge without a lawyer, you need to contact an experienced DUI attorney immediately. Under Florida law you may be able to set aside the plea. If you had an attorney, you need to ask them, or another DUI attorney, about your appeal rights. Based on the facts you describe, it is very difficult to understand how you were convicted of a DUI charge.
Once you clear up the criminal case then you should contact an experienced civil attorney about suing the police for there treatment of you..
