Lawrence resident Paul Veerkamp, of www.localfreetrade.com, announces the establishment of Contractor Exchange, an online service designed to connect building contractors and subcontractors.

The free service allows builders and contractors to post information about their needs and availability, or to check out the availability of others.

The service is available at www.localfreetrade.com. Veerkamp also plans to add a service related to baby-sitting, plus an art gallery.
