You will need an attorney, but in general, a motion fr new trial must be filed within 30 after the conviction was entered. A notice of appeal must also be filed, a request for transcript made, and several other procedural matters must occur, but the primary question that must be addressed is: what is the basis for the appeal, other than you don't like the outcome? The trial court must error to have a conviction overturned. Start calling local lawyers. Good luck.
