If you can draw reasonably well and are willing to teach for free there are lots of opportunities. Bring your work to your library and ask about offering a course or single class to children, adults, or both. Approach your local council on aging (or equivalent) and offer. Churches often host similar events. My family has been to several painting events at a friend's church, and we're not the slightest bit religious. We also help with their set design when they put on plays. Another chance is 4H or scouts. Many of these groups will be able to cover the cost of materials.
Lastly, you probably have a local arts council or equivalent. Our is called a cultural council. They get money from the state to distribute for events just like this. Apply for a small grant.
In any of these cases, be prepared for a variety of skill levels. Also, all of the groups I mentioned will know other groups (Lions, Vets Associations) that might happily host you.
