Without the ability to hire an attorney to handle this, it may be a good idea to contact the folks at your county district attorney's office or sheriff's department, as they might be willing to help you seek restitution or the return of the equipment. Most of the time, law enforcement will try to say such a matter is solely a civil matter, but your facts may suggest otherwise. It just depends on their attitude towards such cases. Just be careful not to threaten to contact police if he does not pay, if you have a civil case pending against him, as this could be considered a crime itself - extortion - under Georgia law.
If this does not work, you could see if Georgia legal services programs operate in your area. If so, they frequently provide legal services for people based on financial need in the context of civil cases. This is not the public defender's office associated with criminal cases.
