I have served almost 6 years of a 10 year probation sentence with no violations or other possibly disqualifying events/behavior
There is NY Legal Aid or Legal Services. They provide pro bono services to those that meet their income guidelines. Their income guidelines are pretty low so it might be similar to those required to get a public defender. You could also contact the local Bar Association as these groups often have names of attorneys willing to take on pro bono cases.
Criminal Defense Attorney
It is extremely rare for attorneys to take on criminal matter pro bono. This is in large part because indigent defendants are entitled to free representation. Though not necessarily entitled to free representation at this point, you should contact the Legal Aid Society they may be able to help. You should also speak with your probation officer. If you have been doing well and otherwise qualify for early termination, your PO can assist with this and you may not need an attorney.
I don't know anyone who does pro bono but the petition process for the release you seek is relatively simple.
Hire a lawyer to protect your legal rights. Good Luck.
