Business Networking Group Needs a Logo Design

We need a logo design for a new social group dedicated to business networking. The group, created by a real estate agent and a financial advisor, is based in Milwaukee and is called 'Business Exchange'. The networking concept is launched from groups like BNI ([login to view URL]) - but is more casual and uses direct recruitment to extend invitations into the group. The group meets monthly for breakfast. It's goal is to cultivate new business relationships across a variety of industries. We would like a clean looking logo - using san serif typeface and some sort of logomark/graphic integration. The design should communicate an exchange in some way.
