I am a web designer and hired an illustrator as a subcontractor to design my client's site some time ago. He put on a registered image that was not paid for. I thought I paid him for it but have to proof of that. My client received a bill for $4,000 for a postage stamp size image on their site. I had no idea this was rights protected and shocked my illustrator would use that type of image. I do not want my client to have the burden to pay and accept responsibility. My problem is I don't have this kind of money. I'm barely surviving. I reported less than $20K on my income tax last year. I can't hardly afford to pay my medical insurance of $500 a month and they want me to sign off on an agreement and send them postdated checks so that they get paid $500 a month until it is paid off. They lowered it to $2,000 and said that is as low as they can go. It's medical insurance or Master File for me. What should I do?
