Has Anyone Had Experience With United Business Solutions based in Muscatine IA?

Hi,

United Business Solutions is a marketing company that offers various services to businesses. Their primary services are recovering overpayments of income taxes and other business related expenses. They do this on a contingency basis. They don't get paid unless they recover funds for the business. Then they keep a percentage of the refund. They offer a business opportunity selling their services to businesses.

Has anyone had any experience with them? I am considering being one of their reps. What would you recommend I do to check them out? Thanks.
