Is there any automatic free logo creator?

Here it is the situation,

I'm making a lot of microwebsites, they should last 1 month, so no big investment in each website, however it has to look credible so it has to have a logo. In this situation I can't afford spending $5 on a gig for each website, so I need something that generates logos, like I give the words that I want on logo and the software generates a lot of logos that I can choose from. Anyone knows some software/website that does that?

Thank you
