[d20-ish] Looking for published skill adventures

[RealMarkP]

I'm trying to put together an adventure that will try to involve the use of all listed skills in the d20/3.P system. In my quest to do so, I'm hoping to find some published adventures that I could pillage or use as inspiration. The system doesn't matter because I can always add my own DCs. What I'm looking for most of all are challenges within a dungeon or urban environment. Target level is 1-5.

Any help is appreciated. Ideas of all kinds are always welcome.
