Collections nightmare on a $2k interstate move from Atlanta to Nashville

Chased this guy for weeks after a $2k job hauling his crap from Atlanta to Nashville, and he's ghosting me now. Sent the final invoice with certified mail like always, but nothing. In Georgia, you gotta file a mechanics lien within 90 days for moving gigs, but this out-of-state BS is screwing me on that.

How long ago was the move? You talking to a lawyer yet or just small claims?
