I had a client move a project to India because he thought it would be cheaper. Eighteen months later he was knocking on my door asking if I could fix the mess. Sadly for me, I tried to help him - I'd have been better to say "no", either immediately or after taking my first look at what had been delivered. The work that had been done (at less than 20% of my hourly rate) was shoddy and not fit for purpose. A detailed analysis showed that the cost of fixing it was about the same as the cost of building it again from scratch. The client then included me in his generalised unhappiness with the consequences of his decision, and I've had no further work from him.
