How can I request alternative sentencing for a felony driving case?

Who do I contact about alternative sentencing in court or before my sentencing for felony traffic. My attorney advised my to take a plea and return to court for sentencing. She stated that the judge would not believe I was not driving because of my backround. There was never a traffic stop. The police came to my home and said that they saw my van going down the block and that I must have been driving. They wrote out a report and I was arrested in my own driveway and had to bailed out of jail. My girlfriend was driving but they would not listen and they told me to shut up and get in police car. My van was towed out of my driveway and now I am facing 30 days in jail. What can I do.
