Use 99 Designs! They are not just for big shots like Tim Ferriss--they are for all the future Tim Ferriss's, too :-). We ran two polls with trusted advisers to finalize our logo contest, and even after picking the winner we were conflicted over three other designs--that's how creative were the submissions. Image spending only $400 to run a logo contest with submissions created by designers competing, worldwide. How about ordering twenty-eight illustrations for your children's book, and having a cover contest to find that illustrator, and having all completed for $1,800? Yes, Virginia, you can do that at 99 designs! Just do it. Just do it. Just do it.
