Abdul Mutakabbir of True and Good Words points us to a very thoughtful site for beginning khateebs:

For a first time khateeb or even a seasoned khateeb, the task of giving a khutbah is very daunting. This is especially true for the first time khateeb. I remember the first time I gave a khutbah, I wished that there was some one-stop resource that I can go to that will tell me all the things I need to prepare a proper, Islamically compliant khutbah. No such thing existed at that time, so I had to go to the local Imam and ask him.

It’s a well-designed website with short guides on drafting a khutbah, complete with duas, and a guide for khateebs. A very handy resource! May Allah reward the brothers behind this effort.
