Abstract: An online auction system enables a consumer to post job description for a job, a second module that enables a plurality of service providers to view the job description and submit a proposal to the consumer for performing the job, and a third module that enables the consumer to select a proposal from one of the service providers. The system may enable the service providers to request additional information about the job from the consumer, and enable the service providers and consumers to interact by modifying the job description and modifying bids based on job description modifications. In some embodiments the system also may provide a job posting template and a payment module.
