With the risks involved with something like this (jail time, fines, etc) I would not move forward without an attorney. Your other option maybe to contact the state police directly to see if you are eligible to purchase a firearm. I am not sure how helpful they will be or can be, but it is worth a shot.
A family member committed a non-violent felony years ago and had his rights restored in Virginia. Unfortunately, his felony was reported to the federal system at some point so he still cannot purchase a firearm or legally possess one because the ATF has not funded any type of restoration of rights program for years. I certainly hope nothing was reported to the Feds or you maybe SOL. Good luck.
