WordML to PDF

We need a process that will take an uploaded Wprd Document Saved as XML (WordML) and turn that into a PDF. We need to make sure the PDF renders CORRECTLY and looks identicle to the Word Doc. We would also need to keep the server installation requirements to an extreme minumum, hopefully none. We could install ghostscript or something similiar but would prefer not to. Another requirement would be that it would have to be done QUICKLY. Hoepfully within 2 days. Please only responde if you can complete this project in full and on time.
