The University of Illinois extension services has put together an online tool to help with tourism development in communities. The link, http://www.communitydevelopment.uiuc.edu/toolbox/ will take you to their toolbox page featuring a link to developing tourism resources in your town, and a tool for assessing your capacity for tourism.
The resources tool is an interactive application that asks questions related to tourism and lets you answer them on the sheet, at the end of the process you will have the start of your tourism plan. The second tool helps assess if your community is ready for tourism. Again it asks questions and you provide the answers.
If you try out these tools let us know how it goes in the comments.
