Job Search System Integration

My client bought a job listing database from a job search engine. The listing is in XML format and he wants to use that data on a Job Board System. He has his own design and wants to adapt it into the chosen system. What he need is to: 1) Fetch XML data and post it in our website's search results. 2) Integrate HTML design into Job Board System. 3) User must have a paid subscription in order to see full job specs. 4) Add Paypal integration to charge for subscription plans. You are free to choose any Job Board System that will let us use the XML data and integrate our design.
