What's a good, FREE background check website?

I'm needing to do a background check. All the sites I go to charge. Is there any 100% FREE sites I can use to run a background check?

Of course not - the folks putting together the background check are doing work and they expect to get paid for doing the work and putting together the product. Expecting to get something like this for free is similar to your employer expecting you to come to work for free.
