doc to .pdf conversion on VB.net Webform

Hi Folks - I have a client that wants to be able to have users upload a word document and then he wants to be able to come behind them later and download that word document as an adobe pdf. So basically he wants me to find out a way to convert a .doc file to a .pdf file. I would perfer a way to do this that would use a component or something small that is .net (so it doesn't have to be installed...restrictions). My question is has anyone ever done this? If so what did you use to do it? Any basic examples? Anything anyone can provide is appreciated! Thanks and Happy Holidays!
