Batching Files together into one PDF (through web interface)

WHAT WE ALREADY HAVE CODED NOW We have created (php based) a website for a career services job fair. Basically, interviewees (or students) register to interview with potential employers. They upload their resume, writing sample, etc. and associate the files with a particular employer. The employers can login, see the students, see the files, download the files, and select the students they would like to interview/hire. you can view at [login to view URL] WHAT WE NEED CODED While employers can view files one by one - we want to provide employers a link (or two, or three if the file gets too big) where all files are combined into one batch PDF file. Difficulties: (1) files will be big; (2) files uploaded are in a number of formats - .doc, .pdf, .wpd. WHEN WE NEED IT Monday :)!
