Does anyone have a simple to set up Word-To-PDF and/or PDF-To-Word script that works using PHP?

I was using a plugin on my site: http://convertaPDF.com and now it seems to be crashing not only the site, but the admin panel and everything. It is calling a file on an external server which appears to have permanently crashed, and so now I must create my own conversion engine.

From what I understand, I must use GhostScript or SOAP... not sure where to begin, so any help will be greatly appreciated.

I hate doing things over again when someone breaks a plugin!
