I had glanced at this before but just took the time to explore the site. This is something I'll play with for many hours when it's done! In the meantime it looks like you need building models? I don't have a lot of time at the moment and can't really commit to helping...but if you'd post specs (model format, poly limit, size, image map size, etc.) and a list of stuff you want I'd be willing to try to put a few together as I have time.
