Build a framework for new website. Proof of concept

Build a proof of concept for a website for nonprofit career counseling agencies. Each agency should have a user account and a landing page/subdomain. Their clients should have user accounts linked to a landing page. User should be able to search for jobs via [login to view URL] or [login to view URL] api or custom RSS feed. Websites should track each application, requisition number, application date and company name. Career counselor should be sent an email with a list of applications for all clients. This is proof of concept where the job search and application tracking are the key details. Jobs need to be tracked by posting company (not job board) and requisition number.
