The WICPA website includes a page that helps businesses and individuals find a Wisconsin CPA based on geographic location, type of business seeking CPA services, type of CPA services sought, and size of CPA firm preferred. Here is the link, in case the link embedded in the previous sentence did not post correctly: http://www.wicpa.org/Content/PublicResources/findacpa.aspx
Also, attached is a template for a 2010 RFP relating to an association seeking an auditor.
I hope this is helpful and welcome any questions you might have.
