First off request this thread be deleted so you can fuck his shit up and there is no proof you did it. If he fucked you over like this he's probably never going to pay. At this point I would just teach him a lesson. People like this are scum. Selling SEO services to offline business owners and don't have a fucking clue what they are doing. People like this fuck shit up for the rest of us that offer legit Offline consulting businesses.
First Step: Blow his site out of the water with xrumer and scrapebox
Second Step: list him on every scam site you can find.
Third Step: Rank these sites for his business name, his personal name
Fourth Step: Create a Facebook profile with his name scammer. Proceed to add all of his friends on Facebook.
Fifth Step: Offer to sell him reputation management ; )

I think creating Facebook Profile with his name and adding his friends and telling about him to his friends will be good and make him to pay me.Good Idea.
