Do I need an attorney to get off probation when on an Interstate Compact?

In 2011 I was sentenced to 10 years probation with one year in prison. I was sentenced under the First Offender Act and was told I had to complete a third of my sentence and pay off my Restitution. When I was released from prison, I moved back to MD with an interstate compact and began supervision there. As of April '15, the restitution is paid. I was eligible for early termination at the end of April. I called the C.S.O for the judge who sentenced me and she had since resigned. I was told by my old lawyer I need to petition the court, but being in MD, that's complicated since I'm a full-time student and work full time. Can a lawyer petition the courts for me or do I need to spend the time and money to petition the courts myself?
