We are in the process of designing our first ad for a "general audience." We are using a site 99Designs to make the advertisement. The process goes something like this: (1) We provide a concept for the ad; (2) Designers do their best to capture the idea; (3) We give feedback, ultimately winnowing the contest down to a few leading candidates; then (4) our friends vote and give feedback in order to determine the winning ad.
There are eight candidates in the running right now. Here is one of our favorites so far. We would love your insight picking the best option. Please click this LINK to see the ads an vote for your favorite.
