wow, what a nightmare. Dude, you gotta do something. sew his ***!
How exactly did he steal it? did you foolishly upload the whole site for him to see before the payment? I always ask my clients to pay for half once I have half of it done. I then show previews of the site to see if they like it or not. I make sure there is nothing they can steal. Then, I only upload the final version once a snapshot of it has been previewed and completely paid for.
