Hmmm... I was planning on doing the research manually, but if you want to share any examples of sites that have gotten better at data extraction, I'm all ears. I will do research as well on that.
At that price, it doesn't seem like you would be able to provide much value by doing it manually. If you factor in some overhead, you would have to be spending less than an hour on each report to pay yourself a decent wage. If I'm running a business, I'm not going to pay someone to do research that I could do myself in less than an hour, even if it is really cheap. With B2B services, it's probably a better idea to provide substantial and demonstrable value than it is to have a really low price.
