A client on a tight budget wanted to start an online store selling jewelry they already sold from their physical store. Long story short, they hired me to modify a Joomla theme, set up VirtueMart, do everything else that needed to be done, and submit their site to search engines. They really wanted good search engine placement but I told them there was more to it than just punching in some keywords. I said I'd be more than willing to work on it but it would mean hiring me beyond the initial price I gave them.
Six months later, they are demanding a 50 percent refund because they claim their search engine placement is poor due to me. They believe they should have that money back to hire someone who can improve their placement.
What would you do?
