Send flyers to schools , libarys, churches, Sr. clubs and nursing homes.
When I had girl scout groups we had kids who just read to seinior citisens who can't read well any more. We did yard clean ups for them too. We planted flowers at a nursing home for them to enjoy.
Did some babysitting so some single moms could have a couple hours to get errands done. There are so many things to do in a community. Good luck and I'm proud to see you began a small bit of service to others.
