So through a combination of tools and bots for websites, some public and some not I have the ability to acquire quite a bit of data (contact information) from many niches. For instance, if someone needed a list of 1,000 contacts that were say... electricians for a particular state. I could provide names, phone numbers, emails, and more for those people in a nice spread sheet. I could also provide owners of businesses in any category in any state in a spreadsheet as well. And all of the information is fairly up to date with little error. I have been doing this for myself for some time, so I know personally that the rate of bad information is VERY low. Is there any value in compiling these lists? Or selling lists to custom order? How would you value this kind of thing? Where would you sell it?
