Travel Cooperative For Charity - Italy

Looking for "tour guides" who might find it interesting or fun to lead groups to local hot spots and places of interest. Milan, Rome, and Florence are on tap. First trip is expected to be in September.

The travelers are not poor. The tour can afford professional guides. But before we go that route I wanted to explore the possibility of finding fun and interesting "amateur" guides who might be enthusiastic to participate, actual expenses paid and a contribution of the balance of the "fee" to the charity of the guide's choice.

Thoughts?
