I want to start a Job (http://javascript%3Cb%3E%3C/b%3E:void%280%29) Board (http://javascript%3Cb%3E%3C/b%3E:void%280%29). The job (http://javascript%3Cb%3E%3C/b%3E:void%280%29) listings (http://javascript%3Cb%3E%3C/b%3E:void%280%29) should appear in a spreadsheet format and I want users to be able to filter the job listings to meet their criteria. As an example, a user may want to see just those jobs (http://javascript%3Cb%3E%3C/b%3E:void%280%29) in California. Or another user may want to see just jobs posted within the last month. I also want Employers to be able to post jobs. I want to give employers the option to post a job for free and an option to post a comprehensive job description for a fee.

Is there any good open source (http://javascript%3Cb%3E%3C/b%3E:void%280%29) PHP MySql script (http://javascript%3Cb%3E%3C/b%3E:void%280%29) out there I can use for this?

Thanks in advanced.
