Your time and energy will be the greatest contribution. An unskilled worker will be just as valuable as a trained professional. Think about what skills and abilities you have and enjoy using that a community could appreciate. What are your hobbies and interests? Do you want to spend more time outdoors; walking dogs, gardening or mowing lawns? Do you enjoy sewing? Or shopping? Are you willing to do ironing while you watch TV? Are there good clothes your children have outgrown? For more ideas look at the Register to see what other people are contributing, as well as what they are looking for.
