Can we arrange a meeting with the DA to settle prior to court, how would we arrange that and what should our approach be to get the fines reduced?

I have been searching the internet for advice regarding some toll violations my wife has in the Austin area. We were negligent in paying them and accept responsibility for our actions. We are not in the greatest financial situation, we are both employed but raising two children depletes any extra money we come across. My wife has been summoned to court on April 18th what advice can you offer us? I've read that they can fine us up to $350 per toll which would literally put us out of our home. Should we get a lawyer? Can we arrange a meeting with the DA to settle prior to court, how would we arrange that and what should our approach be to get the fines reduced? It seems incredibly unfair to charge such an exorbitant fee for a $1 toll. I appreciate your time and any information or advice you can provide to us.
