Try the local schools, a project I worked with (in Bradford)a few years ago, decided to do some May day celebrations which included May pole dancing and we ended up putting an appeal out on local radio which resulted in a school donating a pole they got hidden away in a cellar. We had fun and games teaching the dances though as the person who said they would come and teach the dances didn't turn up, so in the end a couple of co-workers had a quick practice and put together some sort of a display and taught it to the participants and no one was any the wiser, in fact they were asked if they could come and do it again the following year.

Good luck
