Go down to your local county court house and fill out some paperwork (there is usually only a small fee involved). Basically, file a warrant for him with the charge being "Theft by Conversion".
Instead of being arrested, he`ll be sent a summons from the court house to appear where he must state his side (defend himself) and prove that his intentions weren`t to have you do work without the intentions of paying you.
If found guilty, he`ll be arrested on the spot, and since we`re dealing with $1,000.00, its a felony charge.
I know this seems drastic, but for the small fee to file paperwork, once he gets that summons, he`ll be beating a path down to your doorstep to settle your debt.
This is a great tactic for instilling the `Fear of God` in someone and trust me when I say...it works! And "WHEN" he agrees to pay you, make sure to include the `filing fee` too...it shouldn`t cost you more than $50-$75 bucks to file the paperwork.
In my opinion, it doesn`t matter why he didn`t pay you...fact of the matter is...he didn`t pay up and he should be held accountable.
AND...this is cheaper than getting a lawyer
