it's rare that you *need* a mac for anything. the same goes the other way around. File types are application specific and generally not platform specific. Also, pagemaker isn't all that "beefy" of an app. I would find someone who has a copy to sell and just load it on any PC. Last I used it, I was running a 400mhz AMD box with 256mb of RAM. I may still have my licensed version should he need it...
good luck, it sucks being out of work. I know...
