Abstract: A method is disclosed for matching service providers with employers who have work assignments. The method is suitable for implementation on an Internet website. The method provides a mechanism for service providers and employers to negotiate the terms on which service providers and employers enter into contract with each other. The identities of a prospective employer and a potentially interested service provider are kept confidential from each other until both are interested in negotiating. Certain information input to the website is verified by the operator of the website in order to weed out persons who misrepresent their credentials or their identities.
