There are many voluntary jobs available from working for a charity shop to raising funds for a charity event. If you type 'Voluntary jobs' or 'Volunteering jobs' in google, you can find lots information. However, you may want to be more specific about the location and the type of voluntary jobs that you wish to do. For example, if you want to find a voluntary job in London in the fields of environment conservation, you can type those keywords in the google, so you can narrow down your search. Hope it helps and good luck.
