This site has several different collections of people available. Each collection offers a few of the people as free samples.
More recently I also found this website, which offers free samples of people for download as well.
Here is the the link to the rest of our 3d / 2d people resources that we have collected from around the web. Check them all out to get everything you need.
Also, make sure to subscribe so that you can get all the latest free stuff, plus video training etc., whenever it is posted.
