After an informal logo design competition among our think tank members (see results and random internet logo samples we used for inspiration in the attached PDF), we were unable to reach a consensus, therefore we are looking for a fresh set of professional design concepts.
Our ultimate target audience are potential corporate clients for our consulting services.
We are looking for a logo that looks clean (literally and figuratively), and won't pigeon-hole our scope and potential consulting services, which was a concern with some of our initial designs (e.g. Earth in water drop = looks too much like clean water is our focus).
Concerning uses of the logo, aside from our web site (http://www.acleanfuture.com) and business cards, we are looking to add the logo to position papers we will publish, as well as an iPhone app we are working on.
Contact us with any questions -- Thanks!
