Thanks for your question. Knowing how and where to begin community work can be challenging. Based on your question, it sounds like you're interested in learning more about how to introduce and communicate your ideas with potential community partners in the hopes that they will be willing (and perhaps excited!!) to participate in your work. Chapters 6 and 7 of the Community ToolBox focus on "Communications to Promote Interest," and "Encouraging Involvement in Community Work," respectively. Therein, you'll find specific Toolkits on "Creating and Maintaining Partnerships," and "Increasing Participation and Membership." I think this might be a good place to start to get some ideas. As you begin to work through this, please know you can come back to Ask An Advisor anytime with more specific questions, and we will do our best to help you along.
Good luck in your work!
