Our club recently tried to get a logo, as well, and I was amazed how much of a pain it is/was (we decided on a "temporary" logo until something a bit more suitable came along).
I've got to wonder if hiring outside talent is the way to go...
A suggestion?
Take the submissions, put them in front of the steering committee, and vote on it. DON'T submit it for a vote by the membership.
The indecision will cause far more harm than good if you allow everyone to chime in...
It's like taking your kids to dinner: after a bit of whining and bickering, you make the decision for them. Like it or not, they're getting the Happy Meal...
Best of luck!
