Tutorial with john

After my presentation where i mentioned how i would love to be able to produce work that could be used by charities, i booked a tutorial with John as i am really struggling to know who to contact or how to find agencies that work with designers who produce charity based design.

i don't know why i find it so difficult when John takes a few clicks with his mouse and find a whole website with charity agencies....
this was great, at least now i had a starting point to look at each of these agencies and see if any where suitable for what I've been looking for and hopefully get in contact with them!
