Ask HN: Have you ever sued someone you contracted out to do work for you?

Just curious if anyone has contracted work out to another person and if that person has failed/broken the terms of the contract, have you sued them?

In in a nut shell, I have given a person a 30 hour project to create web site templates for a new site that I'm building. I have gotten nothing but the same screenshots of the same files for almost 2 months and it doesn't look anywhere near complete. I'm setup as a C Corp and he is setup as a LLC. I will be speaking with a lawyer Monday if he does not produce the final product by then.

Time frame of the contract specified that it would be 7 to 10 business days. The contract was signed on 9/13.
