Contractor Screwing me Over (but he's bonded)

[Adam Loeb]

And I'm not too sure what a bond is supposed to do..

I hired a guy to do some work for me and was giving him weekly draws, including $20k as a deposit. He'e been paid $70k so far. Hes licensed in GA but not in SC (where the work is), so he's' working under a SC licensed GC

While work was going, we got a stop work order from the city (apparently the actual GC didn't pull the correct permits), we resolved it by getting an architect. 

Now that works about to restart he says something to the effect of "I'm no longer interested."

I have a contract with him and he has a bond.

I want to avoid paying lawyers and having this drag out... Can I somehow sue the bond to get the money back?
