I have a friend who has fallen on hard times. She is an artist, so she thought of opening up commissions to try and get back on her feet. She will draw you pretty pictures for a little bit of money!
That particular tumblr blog is specifically about her Team Fortress 2 drawings, but she will draw pretty much anything from any book/movie/comic/game/whatever, even your own OCs.
You can see more examples of her art here:
