Need Free WordPress Theme

I'm starting to get into WordPress as a side hobby and have had already many offers for paid work however starting with close to no $$ to get into it I'm having trouble getting a nice looking theme going. I can edit/graphically a theme to what I want but finding a good starting "FREE" theme is hard. Do you guys have a site that would have maybe some good free themes to get one started? I heard you shouldn't google "wordpress free themes" as it comes up with some pretty poor and possible virus themes.
